Hi RPereira,
Judging from the word doc that i attached previously, we need to add the additional keyword to specify which subcase and loop to restart from. My guess you are seeing no difference between direct applying subcase 1 and subcase 2 is because the loading condition (force load) and constraint (enforced disp) does not affect each other and can be applied independently. In my case, when restarting from subcase 1, the enforced displacement still holding the center portion of the beam, restrict/prohibit any displacement on that node, while the subsequent force load is applied.
I think the enforced displacement needs to be removed at 1 point of time for subsequent analysis. For example, you can use the pressing and rolling animation shown previously. Initially, a contact is defined to deform the beam. Next, the contact is then removed, before continuing to the next stage. You will need Sol601106 for this.
