UDF and centroid of tetrahedral element

Prabin Pradhananga_22497

Hi experts,

I have been working with UDF for a while. I would like to extract the centroids of tetrahedral elements in the mesh. I have found this link on the acuSolve tutorial.

https://2022.help.altair.com/2022/hwcfdsolvers/acusolve/topics/acusolve/udfgetelmcrd_acusolve_udf.htm

But,  I could not find the routine for centroid.

Do you know how to obtain centroids using quadrature point or is there any routine to directly obtain the centroids of tetrahedral elements?

Thanks.

As in the other question - Nothing in-built for finding or making use of the centroid.  You may be able to extract cell data from the AcuSolve results in ParaView, but there's not much possible from the AcuSolve side.
