How to make a model Rigid during a step

How to make a model Rigid during a step

How to make a model Rigid during a step

(OP)
I have three steps
In step 1 I have displacement field [U]=[U1]resulted for the model
In Step 2 (Heat diffusion-Mechanical Analysis) I want to keep this displacement fixed [U]=[U1] during this step
[U1] (make the model rigid)as I have steady state heat transfer
In Step 3 I want to eliminate this suppression on the [U1]
as transient response will start

-Please note that applying BC :{U}=0 in Step 2 and deactivating it in Step 3 doesn’t solve the issue as Step 3 will start in this case from {U}=0 and not from [U]= [U1]
-It is impractical to use Restart Analysis because this simulating loop is repeated 4 times in the model
Thanks
