Discovery Refine: Results fail to appear after solve in Refine stage.<\/h1>\n
\n

Problem:<\/strong>\u00a0For small cases, results are expected to appear within 10-20 seconds of solving in the Refine stage. If Intel OpenCL drivers are installed on your system and results fail to appear regardless of how long you wait, the problem may be due to a bad driver installation.<\/p>\n

Solution:\u00a0<\/strong>To\u00a0determine whether a bad driver installation is the problem, run this command:<\/p>\n

<ansys-install-location<\/em>>\/Framework\/bin\/Win64\/Ans.DriverSetup.exe –verbose –check- opencl -availability<\/strong><\/p>\n

If your system is set up correctly, the following message appears, followed by one or more entries for the hardware that was found:<\/p>\n

Found OpenCL Platforms:<\/code><\/p>\n

On a problematic system, the following message appears:<\/p>\n

OpenCL Check: Ans.DriverSetup.exe resulted in an unhandled error.<\/code><\/p>\n

To correct a problematic system, you must remove any installed Intel drivers completely and reinstall them directly from the Intel web site. The bad Intel drivers will interfere with the display of solution results regardless of whether you set the system to use NVIDIA or AMD GPUs.<\/p>\n

Ansys has used the following process to correct the problem on some customer systems:<\/p>\n

    \n
  1. From\u00a0www.intel.com<\/a>, download the driver for your Intel GPU.<\/li>\n
  2. Use\u00a0Add or remove programs<\/strong>\u00a0to remove completely all instances of programs with Intel and OpenCL in their names.<\/li>\n
  3. Disconnect your system from the internet.<\/li>\n
  4. Ensure your internet will not reconnect automatically.Doing so ensures that Windows update cannot reinstall a bad driver.<\/li>\n
  5. From Device Manager, find Intel Graphics and select\u00a0Action<\/strong>\u00a0>\u00a0Uninstall device<\/strong>.<\/li>\n
  6. Reboot.<\/li>\n
  7. Install the Intel driver you downloaded in step 1.<\/li>\n
  8. Reboot.<\/li>\n
  9. Run\u00a0Ans.DriverSetup.exe<\/code>\u00a0to verify that the symptom is cleared.<\/li>\n
  10. Reconnect your system to the internet.<\/li>\n
  11. In Discovery, re-solve and attempt to view results.<\/li>\n<\/ol>\n
