The error message states:&lt;\/p&gt;&lt;p&gt;&#8221;Update failed for the Solution component in Fluid Flow (Polyflow). Value was either too large or too small for an Int32.&#8221;&lt;\/p&gt;&lt;p&gt;The project file was originally created by a previous researcher in my lab, and it successfully ran on their system.&lt;br&gt;I am using the same settings and attempting to re-run the project on my computer with ANSYS Workbench, but the solution update fails with the above error message.&lt;br&gt;My system uses ANSYS Student 2024R1, and I am running Workbench with administrator privileges.&lt;\/p&gt;&lt;p&gt;&lt;br&gt;Here is what I&rsquo;ve tried so far:&lt;\/p&gt;&lt;p&gt;Deleted all files in the &#8230;\\dp0\\PFL directory, including .polyflow, .cdata, .lst, and .pfo.&lt;br&gt;Reset the Solution component within Workbench.&lt;br&gt;Tried running the solution update again, but it still failed with the same error.&lt;br&gt;Restarted Workbench in administrator mode and reloaded the project. The issue persisted.&lt;\/p&gt;&lt;p&gt;Changed the Mesh Decomposition from Automatic to 256.&lt;br&gt;Enabled GPU acceleration (nvidia) and increased the processor count from 1 to 2.&lt;br&gt;Modified .p3rc configuration, setting MCONTR to 10 from the default 20.&lt;br&gt;Re-ran the solution update, but the error remains unchanged.&lt;\/p&gt;&lt;p&gt;Switched the GPU setting to none to test if the error was related to GPU acceleration. The issue persisted.&lt;br&gt;Simplified the mesh settings and reduced mesh complexity, but no change in behavior.&lt;\/p&gt;&lt;p&gt;Loaded the original, successful project file directly without any modifications.&lt;br&gt;Reset the Solution and attempted an update. The same error occurs, which suggests that the issue may be specific to my system or ANSYS environment.&lt;\/p&gt;&lt;p&gt;Tried running on a system with administrator privileges.&lt;br&gt;Cleared system-level temporary files and ensured there is enough RAM and disk space available.&lt;br&gt;Verified that ANSYS Student limitations (e.g., mesh size, computational resources) were not being exceeded.&lt;\/p&gt;&lt;p&gt;The same project successfully ran on the previous researcher&rsquo;s system, so the issue seems to be specific to my setup.&lt;\/p&gt;&lt;p&gt;What could be causing the &#8220;Int32&#8221; error, and how do I debug it further?&lt;\/p&gt;&lt;p&gt;Is it related to Polyflow&rsquo;s handling of mesh decomposition or boundary condition data?&lt;br&gt;Could it be an issue with my ANSYS Student version limitations or compatibility with this project file?&lt;br&gt;How can I recover the project after deleting files from the dp0\\PFL directory?&lt;\/p&gt;&lt;p&gt;The error about missing polyflow.dat seems to prevent me from reloading the project correctly.&lt;br&gt;Are there specific diagnostic tools or logging options I can enable in Polyflow to identify where this error originates?&lt;\/p&gt;&lt;p&gt;I&rsquo;ve tried enabling verbose logging (-debug), but I could not identify the root cause from the .lst file.&lt;\/p&gt;&lt;p&gt;ANSYS Version: Student 2024R1.&lt;br&gt;Processor: Intel i7 (8-core).&lt;br&gt;GPU: NVIDIA RTX 3060.&lt;br&gt;RAM: 16 GB.&lt;\/p&gt;&lt;p&gt;&nbsp;&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-394426","topic","type-topic","status-publish","hentry","topic-tag-ansys-error","topic-tag-error","topic-tag-polyflow"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_author_ip":["165.194.11.206"],"_btv_view_count":["477"],"_bbp_topic_status":["unanswered"],"_bbp_subscription":["852","487627","27788","527979"],"_bbp_topic_id":["394426"],"_bbp_forum_id":["27784"],"_bbp_engagement":["852","483226","487627","27788","527979"],"_bbp_voice_count":["5"],"_bbp_reply_count":["5"],"_bbp_last_reply_id":["425289"],"_bbp_last_active_id":["425289"],"_bbp_last_active_time":["2025-03-12 08:18:07"]},"test":"kwg97naver-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/394426","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\/394426\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=394426"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
