how to create the fluid part in DesignModeler
 
Dear all,

I import the geometry created by other CAD tools such as Inventor into DesignModeler, I don't know how to create the fluid part very quickly. I tried the "Fill" tool in DesignModeler. However for simply geometry, it is useful. For complex geometry, I can not use it very well. So does anyone can give some suggestions? Thanks a lot!

try to create a new volume and substract your imported one with a boolean operation. this way should work.

Thanks for reply.

When creating the new volume, should I pick up the surfaces surrounding the volume one by one? If so, this process is time consuming if the geometry of fluid part is complex. Maybe I am not proficient with DesingModeler, I found that picking up faces one by one is very inconvinient.

why picking surfaces? just subtract one volume from the other, or does this not work??

why picking surfaces?
Because I need the surfaces to create a new volume for the fluid part. Otherwise, I don't know how to create a fluid volume.

Thanks.

just go to Tools>Enclosure in Design Modeler. There are many ways of creating enclosure, even your own defined shape.

Thanks.

You are very helpful.

Hi

I have a similar problem , I just thought if you found a solution for it. I have a packing of particles and a fluid surrounding it . I need the design modeler recognize the fluid as a separate zone. Do you have any suggestion?

You can name the 'Fluid' and 'Particles' for the respective volumes in 'Details' Window. these names will be carried throughout the procedure of the simulation also.
