RESTARTW \multiple independent nonlinear subcases. Nonlinear restart requests are not supported.

*** ERROR # 4762 ***
There are multiple independent nonlinear subcases. Nonlinear restart
requests are not supported.

The model is steel, with plastic, non-linear properties.

Without RESTARTW the model runs fine.

With RESTARTW this error message appears.

How can RESTARTs be not supported?

I discovered Optistruct needed CNTNLSUB.

With CNTNLSUB the subcases will be sequential & not independent.

So this problem is resolved now. Thanks
