How to apply one step result as next step initial conditions
How to apply one step result as next step initial conditions
(OP)
It is a two step problem. I need to use the first step results as the second step initial conditions. Althought the geometry and meshing has not been changed, but the material has been changed for the second step.
How can I do with it?
Thanks a lot!

LS1: First step
Apply forces whatever

LS:2 Change Mat.Properties
MPDATA,EX,,,,
MPDATA,NUXY,,,,

The mat.prop change is not an approved strategy but works fine by me. If its a large analysis u can save restart info and start with whatever properties u want in step 2..

BTW, the ANSYS I am using is ANSYS Professional, which doesn't allow nonlinear analysis, is this the reason why I can not carry the results forward?

Do u get any error message ?
btw. The new Workbench9 offers stepped analysis too. Easier to setup...

Do you think this method could be used to run an analysis involving initial stress file (file.ist) and other types of initial condition?
He used to run my script the following way but I am not happy with results
....
read,file.ist
Apply initial conditions
Solve
Do I have to understand the right way is the following?
....
read,file.ist
save LS , solve current LS,
Apply new loads
solve....
Thanks

RE: How to apply one step result as next step initial conditions
U can do it 2 ways:
1:
read,file.ist
(apply loads)
solve
apply loads
solve
..and so on if u are doing it the batch way.
2:
read,file.ist
(apply loads)
save LS1
Apply new loads
Save LS2
solve LS files....
