Hi Fernando!! It’s a very very very interesting idea!!!!!!!!!!!!!!! It can be my solution!! But quite simply I had never used this method. Is there any specific command or I have just to create two model: ET,1,.. and ET,2,..? and after meshing both i let some elements alive and kill the others...

Hi Alex, You were right to specify what is noted in ANSYS help: Between load steps in SOLUTION, material properties cannot be changed from linear to nonlinear, or from one nonlinear option to another. Now, what it’s sure is that it is not right just in the /SOLU but also in the /PREP7. Also, I...

I am disappointed!!! I see that you work on the residual stresses due to welding (you asked lot about that) and now you would like to have an idea on my program. According to your answer I feel that you are not with the height to answer my questions, or those of the others as it is the case for...

hi, I need two materials for the structural analysis. At the beginning, I assign MAT,1 for all the elements. Then in EACH STEP of the structural analysis, I change mat1 to mat2 for all the elements which check a certain condition (according to the temperatures calculate in the thermal...

Hi Alex, I removed LDREAD (I bring back the temperatures at nodes from the thermal analysis and I apply them to the nodes in structural analysis with BF,..), this is less precise but it is correct and it is right to see the effect of LDREAD. Result: the problem always persists. Thus it is ETCHG...

hi Alex! i know that but look: if I do this : !!!!!thermal analysis /PREP7 ..... MAT,1 TYPE,1 ...... /SOLU loads : heat flow .... results : temperature ..... FINISH !!!!!structural analysis /PREP7 ETCHG,TTS ... ALLS,ALL,ELEM MPCHG,2,ALL .... FINISH /SOLU LDREAD,TEMP,,,TIMEXX,1,FILE,RTH ...

Hi everybody. help please!!!! It is my second message for the same problem. At the time of the passage from a thermal analysis to a structural analysis, I use ETCHG,TTS et LDREAD,TEMP,,time,1,file,rth. In the structural analysis, I need to change the properties of the material of the elements...

Hi, Thank you Alex for your assistance. I have another question: In /SOLU I need to do a change in material (MAT1 to MAT2) of some elements and to leave the others such as they are. With MPCHG, ANSYS carries out this change well but does not hold account of this change at the time of the...

hi, I have to resolve a transient thermal analysis. The loadings are heat flows. In /SOLU, a *DO-loop calculates temperatures at nodes for each step. But i need to read these temperatures for each step (before passing to the following). For that, i must use *GET,xx,NODES,yy,TEMP who can be used...
