i want my model first apply eine pretension, then eine pressure ,
in the third subcase, i applied a translation in modell
But the caculation untill subcase 2 ist right, the results of the 3 Subcase would be calculated, but on information depend on the first 2 Step.
Anyone have idee?

SUBCASE 4
LABEL D_Verschiebung
ANALYSIS NLSTAT
CNTNLSUB 2
SPC = 10
NLPARM = 6
DISPLACEMENT(,H3D,,,,,) = ALL
GPFORCE(,,) = ALL
GPSTRESS(,) = ALL
STRAIN(,H3D,,ALL,) = ALL
STRESS(,H3D,,,,,,) = ALL
this my loadstep4, aber the results donot depend on my subcase 2(pressure load)
Altair Employeefor subcase 3 und 4 i have defided the translation als spcadd, ist ok? or must i this translation als load define?
Altair EmployeeSPCADD will combine the SPCs. Are you trying to apply an enforced displacement to translate the nodes?
Hi FalcoW
can you try the below:
1) Create a PRETENSION SUB CASE (image 1)
2) Create a NLSTAT with pressure as LOAD and refer the PRETENSION subcase in STATSUB(PRETENS)
3) Create the translation subcase and use CNTNLSUB with the 2nd subcase which is the pressure subcase.
