How to apply one step result as next step initial conditions

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!

RE: How to apply one step result as next step initial conditions

Just run a 2 stepped analysis.

LS1: First step
Apply forces whatever
ALLS
SOLVE

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

RE: How to apply one step result as next step initial conditions

(OP)
I tried, and it didn't work.
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?
Thanks a lot!

RE: How to apply one step result as next step initial conditions

No, i dont think so. As i can see its only the nonlinear part missing. Normally i just add loads , save LS , solve current LS, Apply new loads , save , solve....

Do u get any error message ?

btw. The new Workbench9 offers stepped analysis too. Easier to setup...

RE: How to apply one step result as next step initial conditions

Hello guys
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
Renaud

RE: How to apply one step result as next step initial conditions

Hi.
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....
