fluid domain problems

[jorritsmit]

Hi all,

im having problems with my fluid domain creation. when i define a fluid domain (extracted with delete face) a get an error saying fluid mesh can't be mixed with soldig mesh. The last time i used coupled thermal-flow i got the same error but assumed it was an error in my part, because it was imported from solid works. This time i build the model from the ground up and it still gives this error. I can't find the solution anywhere, can anybody help?

Dear Jorrit,
You can create a fluid volume using one of these methods:

•Define a sketch representing the 2D shape of a regular fluid volume and then Extrude and/or Revolve the sketch. Use this technique if you know the shape and dimensions of the fluid volume.

•Use Boolean operations to create the fluid volumes. You create a solid representing the enclosed space and select the Unite, Subtract, or Intersect to modify the shape of the volume based on the intersecting solid component geometry. Use this technique if you want to create this fluid volume for single use in an analysis and if you are not interested in maintaining links for geometry updates.

•Create the enclosed fluid volume as a separate part file and component in your assembly file structure using the WAVE Geometry Linker command. This command copies an instance of the geometry of the inner volume and the components from the assembly part file. You then modify the contour to represent the fluid volume by using the Delete Face command (on the Synchronous Modeling toolbar). Use this technique if you want to maintain a link to the geometry of assembly components to allow for geometry updates.

Best regards,
Blas.

I know how to create a fluid mesh and have used two of those methods, but still i get the error message

 

[jorritsmit]

any other ideas? i keep getting the same error on all my other projects to. Even with the tutorial of the PSU

Dear Jorrit,
Upload your model and I will take a look to it.
Best regards,
Blas.

did you find the time yet to look at the model?
