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?

Altair EmployeeCan you share the model?
Altair EmployeeHi,
can you check for stress in your last sub case?
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.
