<p><p>\"\"<\/p><p>When I perform a structural analysis and click the Step 4 Model<\/strong> button, an error pops up, and the program suddenly crashes.<\/p><p>\"\"<\/p><\/p><p> <\/p><p>Below are the steps I took to solve this problem:<\/strong><\/p><\/p>\n

    \n
  1. <p>Deleted the .dmp file:<\/strong><br>After encountering an error with AnsysWBU.exe<\/em>, I noticed that a diagnostic .dmp file was generated. Some suggested that deleting this file might resolve the issue, so I tried this approach. However, the file regenerated every time I opened the Workbench DM module, and the error persisted. This indicated that deleting the .dmp file was ineffective, as it is a system error log that reappears with each launch.<\/p><\/li>\n
  2. <p>Reinstalled the system and ANSYS software:<\/strong><br>Based on online suggestions, I performed a full reinstallation of both the operating system and the ANSYS software. While a few users reported success with this method, most noted it was time-consuming and did not guarantee a fix. After completing the reinstallation, the issue remained unresolved, confirming that this method was ineffective in my case.<\/p><\/li>\n
  3. <p>Registered missing DLL files:<\/strong><br>I opened Command Prompt with administrator privileges and registered scrrun.dll<\/em> using the command regsvr32 scrrun.dll<\/code>. This step was based on the assumption that a missing or inactive DLL might be causing the error. Despite successful registration, the problem persisted.<\/p><\/li>\n
  4. <p>Added system environment variable ANS_OLD_ATTACH = 1<\/code>:<\/strong><br>To address a potential geometry attachment issue, I added a new system environment variable:<\/p>\n
      \n
    • Navigated to Computer<\/em> > Properties<\/em> > Advanced System Settings<\/em> > Environment Variables<\/em>.<\/li>\n
    • Under System Variables<\/em>, I created a new variable named ANS_OLD_ATTACH<\/code> with the value 1<\/code>.<br>This method reportedly worked for some users, particularly for errors like ‘Unable to attach the geometry file… An existing connection was forcibly closed by the remote host’<\/em>, often caused by network issues during mesh creation. Unfortunately, this did not resolve my problem.<\/li>\n<\/ul>\n<\/li>\n
    • <p>Renamed ANSYS-related folders in AppData and Temp directories:<\/strong><br>I suspected that corrupted profile settings, possibly caused by a Windows update, were triggering the error. To address this:<\/p>\n
        \n
      • I navigated to %TEMP%<\/code> and renamed the .ansys<\/code> folder to ansys_old<\/code>.<\/li>\n
      • I also navigated to %APPDATA%<\/code> and renamed the v251<\/code> folders to v251_old.<\/code><br>After making these changes, I restarted ANSYS Workbench. And it didn’t work for me at all<\/li>\n<\/ul>\n<\/li>\n
      • <p>Registered additional system DLL files:<\/strong><br>To ensure all necessary components were properly registered, I ran additional commands in Command Prompt (as administrator):<\/p>\n
          \n
        • regsvr32.exe ole32.dll<\/code><\/li>\n
        • regsvr32.exe atl.dll<\/code><\/li>\n
        • regsvr32.exe oleaut32.dll<\/code><\/li>\n
        • regsvr32.exe scrrun.dll<\/code><\/li>\n
        • regsvr32.exe jscript.dll<\/code><\/li>\n
        • regsvr32.exe vbscript.dll<\/code><br>After registering these files, I restarted the system, but this step alone did not resolve the issue.<\/li>\n<\/ul>\n<\/li>\n
        • <p>Renamed version-specific folders and cleared temporary files:<\/strong><\/p>\n
            \n
          • In %APPDATA%\\ansys\\<\/code>, I renamed the v251<\/code> folder to v251.old<\/code> (adjusting the version based on my ANSYS installation).<\/li>\n
          • In %TEMP%<\/code>, I renamed the .ansys<\/code> folder to old.ansys<\/code>.<br>These changes helped reset user-specific settings. Combined with the folder renaming in Step 5, this didn’t resolve the problem.<\/li>\n<\/ul>\n<\/li>\n
          • <p>Reconfigured ANSYS using ProductConfig.exe:<\/strong><\/p>\n
              \n
            • I navigated to C:\\Program Files\\ANSYSInc\\v150\\commonfiles\\tools\\winx64\\<\/code> and ran ProductConfig.exe<\/em> as an administrator.<\/li>\n
            • First, I selected “Add .NET security exception for ANSYS, Inc products”<\/em> to ensure no security restrictions were interfering with the software.<\/li>\n
            • Next, I clicked “Configure Products”<\/em> and selected all available products for a full reconfiguration.<br>After completing this process, I restarted ANSYS Workbench and confirmed that the issue wasn’t resolved.<\/li>\n<\/ul>\n<\/li>\n<\/ol>\n
