Sequence of loads
Altair EmployeeHi,
I would like to apply 3 loads one after the other, using the diplasement obtained previously. Ho can I proceed? I tried to use CNTNLSUB in the Analysis, but each load is solved regardless the one before. My simulations are non-linear quasi-static.
Thanks!

Altair EmployeeHi,
Yes, this is what I meant.
I don't understand where is the field 'D' in my SPC entry. And i don't understand why I'm supposed to change the *SPC* whereas I want to have a sequence of *loads*.
Thank you!
Altair EmployeeHi LisaWood,
From help '
| 5. | If displacement boundary conditions specified by non-zero SPC or SPCD’s which exist in preceding subcase (say, Subcase 1) are removed in the subsequent nonlinear subcase (say, Subcase 2), then the SPC force resulting from non-zero SPC or SPCD in Subcase 1 would be gradually ramped down to zero in Subcase 2. |
6. If the deformed shape resulting from the preceding subcase requires to be unchanged in Subcase 2, then the D field should be set to “F” on the SPC or SPCD entries.'
Unfortunately there is no way to change with in SPC, but you can edit the deck in any text editor and replace with F
Altair EmployeePrakash I have a question on this issue too.
The SPC card whose D field is to be changed is the one in the CNTLSUB subcase (Subcase2) or the one in the first Subcase? I suppose the second. Correct?
Altair EmployeeHi,
Yes, it is on the second subcase.
Altair EmployeeHi Prakash,
Thank you very much!
Hi,
Do you mean no information is carried from 1 subcase to another?
If the deformed shape resulting from the preceding subcase requires to be unchanged in Subcase 2, then the D field should be set to “F” on the SPC or SPCD entries.
