I am new to Caedium and I have several parts and assemblies in Solidworks and would like to know if I can open them in your program so that I can run CFD on them?
Your best option to transfer geometry from SolidWorks to Caedium is via STEP:
If you have ready access to SolidWorks you might find it easier to prepare your flow volume in SolidWorks.
For internal flows, such as a the water flow through a pipe, you will need a solid model of the internal path the fluid will take. For a detailed tutorial try "Pipe into a Box" and the follow-on "Incompressible Flow Through a Pipe into a Box"
For an external flow, such as the air flow around a wheel, you need to subtract the wheel from a large box. For a detailed tutorial try "Wheel in a Box" and the follow-on "Flow Over a Rotating Wheel with Moving Ground"
I should also add that you will need to activate (through a trial or paid subscription) either Caedium Professional or Caedium Exchange add-ons to enable the STEP import in Caedium.
