Hello,
Recently DesignBuilder team identified that in some machines Windows have altered the priority of the simulation process. The development team implemented an improvement to address this Windows limitation in the latest v7.3 release.
For older versions you can manually set the registry key on the pc as described below:
Open “Run” (windows key + R)
Type “regedit” and press enter.
At the top search area type in “Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options”
Right-click “Image File Execution Options” -> New -> Key
Name the new key “RunEPDLL.exe”
Right-click the new key and do again -> New -> Key
Name this key PerfOptions
Right-click on this key and press New -> DWORD (32-bit) Value
Name this key CpuPriorityClass.
Double-click this key and put 3 in “Value Data”
Then run the simulation.
I hope this helps.
Luis
