Hello Guys,

I am really new to OpenFOAM. I need to simulate a fluid flow inside a tube. Please recommend a CAD software where i can design a geometry and download in seperate .stl files? eg: inlet, outlet and the tube

Thanks in advance!

Salome is a commonly used CAD software for use with openFoam. It has it's own meshing capabilities too.

AutoCAD, FreeCAD, OpenFoam's own BlockMesh, Salome.

You want seperate .stl files for your mesh? That might not work with OpenFoam. But you could do the meshing with salome, which can create different patches from an stl.

Maybe I do not get your statement correctly but *.STL files are a common geometry data for OpenFOAM in combination with snappyHexMesh.

You are right Tobias. Seems my answer was misleading.

As i understand OP want's to use seperate .stl files to form one geometry. From my experience, using three seperate cylinders to form a larger one, snappyHexMesh struggles to mesh multiple .stl files into a meaningful topography. I, at least, never got it working.
