workbench set element typs 1

[medinas]

Hello, I am trying to conduct a study of a heat exchanger with change of phase.
Already draw the areas in ansys wbe, and then to import the environment, it generates a simulation mesh automatically with elements of the type plane77 I wanted plane55 type of elements. How I can do that change?

Somewhere under the Mesh portion in the model tree you'll have to specify that you want quadratic elements, not linear. It should be relatively easy to find.

I have been look at options and even in the help and can not find this option, you can tell where I can find it.

Thanks

Hi,
as long as you only want to "substitute" an elem type with another, you could possibly do like that:
1- Define a Selection Group including only but all the elements you do have to substitute
2- In the Simulation tree, together with the boundary conditions, insert a "Commands" snippet. The APDL commands defined herein will be executed right after the /solu command and before the "solve" command.
3- In order to "intercept" Workbench and re-enter preprocessor, write your commands snippet somehow like that:
/PREP7
<definition of element number 90 (for ex.) of type PLANE>
CMSEL,s,<name of the selection group>
EMODIF,... (see Help for the correct syntax in order to change the element type number only)
/SOLU

There may be some more tricks to input in order to deal with the midside nodes: if I understand well, PLANE77 is linear while PLANE55 is parabolic; anyway, Ansys has an APDL command to generate midside nodes.
