How to export surface pressure from AcuFieldView or AcuSolve to FEA solvers

Altair Forum User

Hi,

 

I would like to export these pressure values from AcuFieldView or AcuSolve to FEA solver, how can i do that..?  Please help me regarding the same.

Hi Sandeep,

 

Please find the attached documents which explains how to map pressure to a structural solver.

let me know if you face any problems in mapping.

hello guys,

 

im having an issue while using AcuSolve cmd promt.
 

i can not create variables nodes neither run the command acuPython acuGetNodeSubset –h.

 

The programs show me the error in the picture below.

can you guys help me.
P/S: i already placed acuGetNodeSubset file in my working directory.

 

 

acupro

If you first use 'cd' to go into the directory where you placed the acuGetNodeSubset python script itself, you should be able to use

 

acuPython  acuGetNodeSubset  –h

 

in that directory, rather than issuing it from the 'Documents' directory as in your snapshot.

Thank you so much!

I couldn't find  acuGetNodeSubset python code in my installation directory or anywhere else in my pc. So, Where can i get acuGetNodeSubset Python file.

 

It would be great if you help me out with this.

acupro

acuGetNodeSubset should be in the /script/ directory of the installation.

Tq for reply. I couldn't find it my installation directory.  Luckily I got it from Forum memeber.

Just curious - which AcuSolve version are you using, and on which OS?

Hi Everyone,

 

GetNodeSubset gets the data at the nodes. Is it possible to get data at cell centers?

AcuSolve stores the data at the mesh nodes rather than the cell centers.  What are you wanting to do such that you want data at a location other than the mesh nodes?  In other words, why would the data at the mesh nodes not be sufficient?

Thanks for your reply. IMO there should be no difference between the two , since CFD works on conservation principles. I cannot disclose much, but I need to map pressure data (from another CFD code) to structural mesh in HM. I am getting some deviation in my results. Hence, I want to check if i can get the same data from Acusolve and try mapping in HM and may be the deviation is gone.

If you only need to map/interpolate the AcuSolve data onto another mesh, you should be able to use the load mapper and/or linear interpolation process within HyperMesh using the nodal data from AcuSolve directly, rather than going through two different interpolations.  There are a few different topics on that in other forums describing the process to extract the surface data from AcuSolve results and map/interpolate in HyperMesh - or refer to the initial question and response above in this topic.

You could potentially use the acuInterp utility within the AcuSolve distribution to interpolate the data to a point cloud, but you would need to build that point cloud as there is no AcuSolve script/utility to do that for you.
