Solid Region issue while creating external flow volume

I am trying to create an external flow volume around this block. But when I apply the dimensions of the external flow volume, I get an error saying, “No solid region could be used to create the flow volume. Please make sure to select solid regions or try to thicken or extrude sheet bodies to make them solid.” My CAD is a full solid body and for defining hte external flow volume, I am excluding the block from the external flow volume.

Hi,

For this particular case, since the only volume that you have needs to be excluded from the flow volume creation operation, it wouldn’t be possible to create the flow region in SimScale with this exact geometry.

The operation needs at least 1 solid part to generate the flow region. Some work-arounds:

  1. You can simply create the flow region directly in your CAD tool
  2. You could add one volume representing the floor, just so it can be used as a seed face for the operation

Otherwise you will keep running into errors.

Cheers
