Not deleting note with loading while deleting other isolated notes

Anonymous — Wed, 06 Mar 2019 02:54:31 GMT

Hi, I would like to know how not to delete the notes with point load if I want to delete other isolated note in the model. I want to delete isolated nodes and recreate the meshing of model but also want to keep these point load on a slab.

Thank you.

I find the real problem now, the loading on isolated note is not applying on my structure.

Is it possible for me to apply a point load on a membrane member?

Yes, it is . You should use "Force in Point" on load definition.

But there is no calculation nodes on membrane member, and then no result for that load case.

In membrane member, you can't have loads, because by definition that type of element is used to ensure compatibility conditions between nodes. You have to define cladding elementes if you want to apply loads.

See help file that of point load that says "This type of load acts on planar elements; it may also be distributed on bars if it is applied to a surface which is a cladding (then the load distribution according to the trapezoidal and triangular method is only possible"

Hi @Anonymous ,

Unfortunately, at the moment it is not possible to filter nodes like you want using 1 button click. You mat try following approach:

1. Get numbers of nodes with loads from Load table. I would recommend to export to Excel and use filters. However, this task can be solved using API (I hope)

2. Go to Selection dialog (Edit - Select) and create group for your nodes with load:

3. Now select isolated nodes, select created group and press "-":

All nodes with loads will be excluded from the list of isolated nodes:
