Generate "fluid" geometry

  • Which feature do you need?
    It would be great is Simscale could generate basic “fluid” blocks/geometry around parts.

  • What is the problem that you want to address with this feature?
    Though, I understand Simscale should not be a CAD software, most 3d parts come without a “fluid cavity” for air or liquid flow. Some basic CAD programs don’t even have this feature. It would be great if we could just draw a cube around CAD model and the Simscale would turn those into the fluid mesh with mapped boundaries. This seems to be a “simulation specific feature” rather than a “part design feature”. it would be appropriate for Simscale to implement.

  • What is the expected outcome?
    Draw a block around a parts model and it becomes a block of air/fluid.

  • Can you share application examples, ideally with project links on SimScale?
    My CAD software doesn’t have a cavity feature. I want to draw that airblock in Simscale and have it mesh and map faces automatically.

Hi @gsonnenf,
today is your lucky day! This feature already exists as “Geometry Operation” on SimScale - check out the documentation: How to Create Flow Volume Extraction? | Knowledge Base | SimScale

Let us know if this does not cover all your needs!

Best,
Richard
