Using the problemtype with an example

We will repeat the same as for the classical use example

• Create or import the geometry (pentagon of classical case)
• Load the problemtype: menu Data -> Problemtype -> cmas2d_customlib

and show its tree in case it is hidden, with the menu Data->Data tree

• Choose in the tree Properties -> Shells

a frame on the bottom of the tree will allow to select the material: Air and expect to be assigned to groups of entities.
In general a recommendable workflow is to create first the groups of entities and to apply in a second step the calculation properties to these groups, but for simple cases it is possible to create automatically the group during a selection, pressing the Select button

• Click Select and select the surface. Press <Esc> when this step is finished, and then press Ok to validate it (the automatic group name could be changed before its validation)
• Choose then Point Weight, and the frame to assign it to points will be showed

• Enter the value 1e3 in the Weight box. Click Select and select the upper corner point. Press <Esc> when this step is finished, and then Ok to accept it.

with the menu: Utilities -> Layers and groups you can open the groups window, and see that the selection has created a couple of new groups, with automatic names based on the data tree items.

• Choose the Mesh -> Generate option, use the suggested mesh size value
• Save the model with a name, to allow the calculation program write its result files in the case folder.
• Choose the Calculate option from the Calculate menu to start the calculation module.
• Wait until a box appears indicating the calculation has finished.
• Select the option Files-> Postprocess.
• Visualize the desired result like the classical example.
