Hi,

u could write a parser from Matlab to Ansys APDL (using the

Sphere Command (https://www.sharcnet.ca/Software/Ansys/16.2.3/en-us/help/ans_cmd/Hlp_C_SPHERE.html)) for generating you different spheres in ANSYS.

Hi Christian Schubert

Thanks for your reply. Following your suggestion, I tried with some examples, but how can I do it with more than 200 spheres.

Hello Boujlal Ayoub ,

you can use the following Syntax in Ansys Mechanical APDL with File->read Input from->:

/BATCH

/COM,ANSYS RELEASE Release 19.2 BUILD 19.2

/input,menust,tmp,

/CLEAR

/PREP7

WPLANE, , 0, 0, 0, 1, 0, 0, 0, 1, 0

SPH4,0,0,0.01

WPLANE, , 0, 0, 0.1, 1, 0, 0, 0, 1, 0.1

SPH4,0,0,0.02

WPLANE, , 0, 0, 0.2, 1, 0, 0, 0, 1, 0.2

SPH4,0,0,0.03

FINISH

This principaly will generate 3 SPHERES in Ansys and could possibly be extended to a arbitrary number of spheres. I don't really know if the number of volumes is limited in Ansys, since the simulation of so many bodies is a very unusual case, but if there is a limit you may find better help in the student community forum (https://studentcommunity.ansys.com/) or if you have a full licensed version at the customer support of Ansys.

Hello Christian Schubert

I find another way.

Thank you for your answers
