run ACM in examples error #18

Open fancycatywh-cpu opened 3 years ago

fancycatywh-cpu commented 3 years ago

I try to run ACM rocflu example, but crashed after a while with information something like "mesh too distorted". is there any problems with the example?

@fancycatywh-cpu Could you check if the ORDER parameter in ACM.inp file is set to 1?

I will try it. But i think that grids will always become too distorted as grid moving more and more, when i run a motor with star-shaped grain, i find this problem. Is it true that i can only calculate a motor for transient time without remesh? respond for your reply.

The embedded remeshing feature was not robust, and was used only in research studies. It has been removed from the Rocstar software for the moment. We are working on developing a new remeshing approach, but it is not yet included in the software.

I also meet fail about test ACM, it seems like I don't have enough memory. But I don't understand why I just set 384bytes (My machine is 4GB memory)and the maxvwgt. Requested size: 171798691848 bytes. I want to know where I can set the memory size.
