meshing "mapped"

[pitizone]

Hi every body,

i have a simple problem and I need your help.

I have a part with a simple shape: it consists of differents volume with cubic shape.

But when I want to mesh my body using "mapped" option, Ansys write an error; He tells me that my body can't be mesh with this option. I don't know why he tells me that.

can you help me?

thanks

Mapped meshing means that opposing lines have the same number of elements. Could it be that you already meshed opposing lines with a earlier mesh command and this does not work out?

No, my body isn't meshed. I create my geometry and that's all.

It's strange because I can mapped my body using Workbench but when I want to mapped using Ansys classic, there is an error.

if you want to try to mapped the body, I join code file

Hello,

problem solved! You had one error: you have issued VADD instead of VGLUE. By VADD you are getting only 2 volumes with very complicated shapes.

Just an advice: VSWEEP is working much better then VMESH, when it comes to mapped mesh volumes.

See below.

thanks alex

I'm a new user of Ansys and there are a lot of commands and options. It's not very easy...

thanks again
