How it is possible to consider some special elements in one step?

How it is possible to consider some special elements in one step?

How it is possible to consider some special elements in one step?

(OP)
Hi,


I want to do an analysis in which I have two steps. The question is I want to know how it is possible to consider some special elements in one step. I have attached a simple model regarded to this question.


In the file attached, I considered a sheet in which a 30N force is applied in Y direction in step1. I want to have a load in X direction in step2 (20N) with the new boundary condition. The thing is that I want to omit the left half of the sheet in step 2 and just consider the right half of that in this step. But I do not know how it is possible to delete some elements in one step and do not consider them.

Did you look at the keyword
*Model change
?
You will be able to remove of reactivate elements during an analysis.

Would you please let me know how can I use this keyword?

I have checked ABAQUS user manual and it is mentined that I should use "Interaction module: Create Interaction: Model Change: Definition:Region, Activation state of region elements: Reactivated in this step", but I could not find this keyword in interaction. I have not used keywords in ABAQUS. Please let me now how can I use keywords in ABAQUS?

Sorry for the late response.
You should do that by modifying your input files (.inp) because I do not think this is available in CAE.
Input files consist of keywords with arguments such as
*Node
      1,          11., -0.600000024
      2,           0., -0.600000024


Good luck
