Previously, I used Ansys Fluent with constant flow parameters, but I needed to calculate the dependence of the drag force (Fx) on the inlet flow velocity.&lt;\/p&gt;&lt;p class=&#8221;first:mt-0 last:mb-0&#8243; dir=&#8221;ltr&#8221; style=&#8221;text-align: justify;&#8221;&gt;First, I found that there isn&rsquo;t much information online about performing such parametric studies, and many people, like myself, encounter errors during the calculation process. I decided to describe the main solutions I found, compare the results, share them with others, and perhaps discuss some aspects. Someone might even suggest a more efficient solution.&lt;\/p&gt;&lt;p class=&#8221;first:mt-0 last:mb-0&#8243; dir=&#8221;ltr&#8221; style=&#8221;text-align: justify;&#8221;&gt;Let&rsquo;s start with the problem. The task was quite complex, and the solution process is time-consuming, so I decided to consider a simplified version: supersonic flow around a sphere in a 3D setting. The sphere&rsquo;s radius is 5 mm. To accelerate the calculations, half of the computational domain was considered. The geometry is shown in Figure 1, and the mesh in Figure 2.&lt;\/p&gt;&lt;p class=&#8221;first:mt-0 last:mb-0&#8243; dir=&#8221;ltr&#8221;&gt;<img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/i.redd.it\/0t1eowcoevge1.png\" alt=\"rich text editor image\" width=\"391\" height=\"477\" \/>&lt;\/p&gt;&lt;p class=&#8221;first:mt-0 last:mb-0&#8243; dir=&#8221;ltr&#8221; style=&#8221;text-align: center;&#8221;&gt;<em>Figure 1<\/em>&lt;\/p&gt;&lt;p class=&#8221;first:mt-0 last:mb-0&#8243; dir=&#8221;ltr&#8221;&gt;<img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/i.redd.it\/68160dcpevge1.png\" alt=\"rich text editor image\" width=\"396\" height=\"475\" \/>&lt;\/p&gt;&lt;p class=&#8221;first:mt-0 last:mb-0&#8243; dir=&#8221;ltr&#8221; style=&#8221;text-align: center;&#8221;&gt;<em>Figure 2<\/em>&lt;\/p&gt;&lt;p class=&#8221;first:mt-0 last:mb-0&#8243; dir=&#8221;ltr&#8221; style=&#8221;text-align: center;&#8221;&gt;&nbsp;&lt;\/p&gt;&lt;h1 class=&#8221;text-24 leading-7 mt-large mb-x6&#8243; dir=&#8221;ltr&#8221;&gt;Method 1 (Benchmark)&lt;\/h1&gt;&lt;p class=&#8221;first:mt-0 last:mb-0&#8243; dir=&#8221;ltr&#8221; style=&#8221;text-align: justify;&#8221;&gt;The first, most obvious, most stable, and 100% correct method (which we&rsquo;ll take as the benchmark) is to calculate each case separately, as shown in Figure 3.&lt;\/p&gt;&lt;p class=&#8221;first:mt-0 last:mb-0&#8243; dir=&#8221;ltr&#8221;&gt;<img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/i.redd.it\/2r2vpbeqevge1.png\" alt=\"rich text editor image\" width=\"974\" height=\"610\" \/>&lt;\/p&gt;&lt;p class=&#8221;first:mt-0 last:mb-0&#8243; dir=&#8221;ltr&#8221; style=&#8221;text-align: center;&#8221;&gt;<em>Figure 3<\/em>&lt;\/p&gt;&lt;p class=&#8221;first:mt-0 last:mb-0&#8243; dir=&#8221;ltr&#8221; style=&#8221;text-align: center;&#8221;&gt;&nbsp;&lt;\/p&gt;&lt;p class=&#8221;first:mt-0 last:mb-0&#8243; dir=&#8221;ltr&#8221;&gt;This method requires setting up one calculation case and then copying it, changing the flow velocity (Mach number).

However, for other cases, there&rsquo;s almost a twofold increase in the number of iterations; in the last case, the number of iterations reached 1748! The Fx values also do not match the benchmark; the difference reaches 10%. This is caused by the default initialization method; the program attempts to initialize each design point with the solution of the first one (or the one selected when starting the calculation), which causes errors.&lt;\/p&gt;&lt;p class=&#8221;first:mt-0 last:mb-0&#8243; dir=&#8221;ltr&#8221;&gt;In conclusion, I strongly discourage using this method for such tasks.&lt;\/p&gt;&lt;p class=&#8221;first:mt-0 last:mb-0&#8243; dir=&#8221;ltr&#8221;&gt;&nbsp;&lt;\/p&gt;&lt;h1 class=&#8221;text-24 leading-7 mt-large mb-x6&#8243; dir=&#8221;ltr&#8221;&gt;Method 3 (Also Bad)&lt;\/h1&gt;&lt;p class=&#8221;first:mt-0 last:mb-0&#8243; dir=&#8221;ltr&#8221;&gt;This method differs from the second only in one aspect.

However, the discrepancies in the force values compared to the benchmark are still around 10%, which I believe is due to the inability to finely tune the initialization method for each Design Point. I assume that in this case, the program chooses Standard Initialization as the initialization method, as it was chosen for the zero Design Point, but it does not consider the Compute From parameter during initialization, and this can create additional problems during the solution. I also note that the Scaled Residuals graphs behave somewhat differently compared to the benchmark solutions; when solving my main (complex) problem using this method, several points did not converge at all!&lt;\/p&gt;&lt;p class=&#8221;first:mt-0 last:mb-0&#8243; dir=&#8221;ltr&#8221;&gt;&nbsp;&lt;\/p&gt;&lt;h1 class=&#8221;text-24 leading-7 mt-large mb-x6&#8243; dir=&#8221;ltr&#8221;&gt;Method 5 (Better)&lt;\/h1&gt;&lt;p class=&#8221;first:mt-0 last:mb-0&#8243; dir=&#8221;ltr&#8221;&gt;I also found online information stating that a parametric study can be launched directly in Fluent, but to do this, it must be launched as a separate application, not through Workbench.&lt;\/p&gt;&lt;p class=&#8221;first:mt-0 last:mb-0&#8243; dir=&#8221;ltr&#8221;&gt;First, export the computational mesh to a separate file, open Fluent as a standalone program, and import the mesh file.

However, the output parameter (Fx) column retains the calculated force values, which can be used later.&lt;\/p&gt;&lt;p class=&#8221;first:mt-0 last:mb-0&#8243; dir=&#8221;ltr&#8221;&gt;But what if I need the results of each point, not just the force value? In this case, we need to add to our script the recording of each solution to a separate file. Start Record Journal, right-click on any calculated Design Point, and click Export Selected Design Points (Figure 19).&lt;\/p&gt;&lt;p class=&#8221;first:mt-0 last:mb-0&#8243; dir=&#8221;ltr&#8221;&gt;<img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/i.redd.it\/hibr2v56fvge1.png\" alt=\"rich text editor image\" width=\"764\" height=\"442\" \/>&lt;\/p&gt;&lt;p class=&#8221;first:mt-0 last:mb-0&#8243; dir=&#8221;ltr&#8221; style=&#8221;text-align: center;&#8221;&gt;<em>Figure 19<\/em>&lt;\/p&gt;&lt;p class=&#8221;first:mt-0 last:mb-0&#8243; dir=&#8221;ltr&#8221; style=&#8221;text-align: justify;&#8221;&gt;&nbsp;&lt;\/p&gt;&lt;p class=&#8221;first:mt-0 last:mb-0&#8243; dir=&#8221;ltr&#8221;&gt;nd the recording; the program will save the solution as a separate Workbench project in the folder with the main project.

It allowed for almost complete agreement of results, but it is not without its drawbacks, as it requires additional steps to record the script and additional saving of each point.&lt;\/p&gt;&lt;p class=&#8221;first:mt-0 last:mb-0&#8243; dir=&#8221;ltr&#8221;&gt;&nbsp;&lt;\/p&gt;&lt;h1 class=&#8221;text-24 leading-7 mt-large mb-x6&#8243; dir=&#8221;ltr&#8221;&gt;Conclusion&lt;\/h1&gt;&lt;p class=&#8221;first:mt-0 last:mb-0&#8243; dir=&#8221;ltr&#8221;&gt;In summary, the most preferable method for conducting a Parametric Study is the last one (using a Python script file). Methods 4 and 5 might work well with Hybrid Initialization, as this initialization method lacks additional parameters. I hope this information will be helpful to someone.&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-408068","topic","type-topic","status-publish","hentry","topic-tag-fluent-ansys-1","topic-tag-fluent-cfd-ansys-1","topic-tag-fluent","topic-tag-parametric-analysis","topic-tag-parametric-study-1"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_forum_id":["27792"],"_bbp_topic_id":["408068"],"_bbp_subscription":["510256","2404"],"_bbp_author_ip":["37.220.85.176"],"_bbp_last_reply_id":["408493"],"_bbp_last_active_id":["408493"],"_bbp_last_active_time":["2025-02-05 14:35:25"],"_bbp_reply_count":["1"],"_bbp_reply_count_hidden":["0"],"_bbp_voice_count":["2"],"_bbp_engagement":["510256","2404"],"_btv_view_count":["1562"],"_bbp_topic_status":["unanswered"],"_bbp_likes_count":["2"],"_edit_lock":["1738580002:510256"]},"test":"nicemarkindgmail-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/408068","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics"}],"about":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/types\/topic"}],"version-history":[{"count":0,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/408068\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=408068"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
