Hello Everyone,

I did a curved rectangular plate modelling in Ansys Apdl using commands input. Although, the line loads are applied to the model properly according to the coding , but the model is not getting solved. But, if I give the loads manually on individual nodes the problem is solving. So, I guess some where mistake in load data commands which can't be identified.

'a' - width, 'Ra' - Radius.

Kindly, find below the coding for model.

So, it would be great if someone can help on this whether need to add some commands on the load section.

Thank You
