Midmesh for Modal Analysis

ALI_22271

Hello,

I am preparing this component for a modal analysis
I did a midmesh, and generated different properties (same material but different thickness)
How can I manage to assign different properties to the same component ? is it possible ? if not what do I have as an alternative ? 

Thanks

You can use 'Map Thickness' tool to assign thicknesses from your input solid geometry.

It can assign thickness to your Component (by breaking it into different comps), or keep the same component but add elemental/nodal thickness to your model, through direct assignment.

 

Please take a look at the documentation of this command as well.

This is valid also in Hypermesh right ?

Ctrl+F >> 'Map Thickness' should point you to the tool in the old interface as well.

With classical GUI, you can go to the panel "2d" => "midmesh":

and then "thickness map..."

Exactly, but my question is as follows:

when I have more the 1 created property (2,3 or n properties) how can I assign these many properties to only 1 component ? knowing that all the thicknesses are all of the same component.

Thanks again

You can not assign multiple properties to ONE component. You have to split this component into several sub-components before applying one property for each new component.

HyperMesh allows you to work in 3 ways:

- assign property into the Component (Indirect Property), and all elements get this property assigned. In this case you need to break your part into smaller comps to get different properties per region.

- assign property directly into the elements (Direct Property): you select a few elements and assign a specific property into these elements directly, independently of the component it belongs. So you can have a single component, but multiple properties assigned

- assign nodal thickness directly into your elements: depending on your solver, you can enable nodal thickness and select a bunch of elements and edit their  nodal thickness individually. This goes directly in the element, when you do 'card edit'.

 

Map Thickness tool allows you to do all of the above, under its preferences.
