I have checked the forums and have not found a viable solution yet. One of the people has the same problem as me under this forum for ‘ANSYS Products’, but I couldn’t understand how they solved it because it seems they are using Linux and I use Windows. Another person with the same problem as me in the forum for ‘ANSYS Free Student Softwares’ has their posts replied, but I couldn’t access it because it denies me even opening the page. My last solution is to make a new post myself.<\/strong><\/p>\n

So…I downloaded ANSYS Free Student Software to learn Workbench and Fluent. Fluent and the other applications work well, and I have no problems opening them except for Workbench alone. Whenever I open the workbench, the same unexpected error comes up no matter what I do.<\/strong><\/p>\n

It loads all the plugins, initializes then instant error.<\/strong><\/p>\n

“Unexpected error: The type initializer for ‘Ansys.Core.Expressions.ExpressionEvaluator’ threw an exception.”<\/strong><\/p>\n

The same error over and over again. How can I get my work done at this rate? Then, whenever I open the ‘Show Details’ button. This is what comes up.<\/strong><\/p>\n

Solutions I tried:<\/strong><\/p>\n

    \n
  1. Reinstalled 5 times to be exact.<\/strong><\/li>\n
  2. Redownloaded the software from the website and then reinstalled it.<\/strong><\/li>\n
  3. Restarting my computer.<\/strong><\/li>\n
  4. Checking my environment paths, and they linked correctly.<\/strong><\/li>\n<\/ol>\n

    All the above solutions were done, and not a single one worked. I am annoyed. I want to contact support but cannot, and it directs me to this because I have the student software. Can someone help me?<\/strong><\/p>\n","protected":false},"template":"","class_list":["post-233221","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["261672","68381"],"_bbp_author_ip":["23.218.93.111"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["3559"],"_bbp_status":["publish"],"_bbp_topic_status":["unanswered"],"_bbp_topic_id":["233221"],"_bbp_forum_id":["27796"],"_bbp_engagement":["68381","261672"],"_bbp_voice_count":["2"],"_bbp_reply_count":["4"],"_bbp_last_reply_id":["233793"],"_bbp_last_active_id":["233793"],"_bbp_last_active_time":["2022-08-25 15:00:25"]},"test":"din_hnoutlook-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/233221","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\/233221\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=233221"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
