hello everyone.
I wanna start learning GridPro now. and I have seen a video meshing a symmetric volute. it seems GridPro handles this situation very well. but most of the volutes in actual are asymmetric, also called overhung volute. is there any video or tutorial for an asymmetric volute?
compared to ICEM, which one is better for an asymmetric volute?

Hi,

Can you share the image of your geometry so that I can guide you better?

Chitra

hello Chitra:
thanks for your reply.
here is the symmetric volute, for which i can create the mesh by ICEM.

the cross section is a circle symmetric to the center plane of the diffuser:

and the topology of the volute is like this:

it's not very difficult to mesh such a volute. but now the volute i want to mesh is asymmetric, also called overhung volute in some papers:

the cross section of the volute is a circle biased to one side:

i still cannot find a proper way to mesh an asymmetric volute. and it really takes time.
thanks again.

Asymmetric volute can be very well meshed in GridPro and it is quite similar to the ICEM blocking. Since GridPro offers both Top Down and Bottom Up, the blocking can be quickly translated/copied to the asymmetric part. If possible share the geometry.

sure, i will share the geometry. can GridPro accept IGES file, or some other format?

GridPro takes stl format as an input file. You can share the file either in stl or iges or step format.

may i get your email? i cannot attach the STP or some other format on the text, for its size exceeds the limit of the forum.
