Distorted Element issue

[tt501613]

When I try to load a concrete wall with a hydrostatic load I get a distorted element error and Robot will not run.  The screen shots below show what I get.  The wall  is not restrained at the top but is along the other edges.  I have tried several different kinds of restraints with no luck.  Help.

Distorted element waring shows a problem with FE mesh . Click on the waring and it will probably highlight where the problem is

Thanks Rafacascudo

It does highlight a mesh but I have tried everything I know to fix the problem but nothing helps.  I have remeshed the wall with smaller mesh sizes, and I tried the Correct command under the Edit menu but that does nothing as far as I can tell.

zip and attach the model ,if possible

Thanks for your help on this.

Attached is the file.

your model is done on "plate" strucuture type and has no loads or supports.

Use "shell" structure type and it shall work with no problems

Still having problems...obviously I am new at running Robot.  Thanks again for your help.  See attached for my latest try.  Interestingly, I noticed I get a deflection on the pressure side of the wall, however still no results.

the only problem on your model is that your chosen thickness (TH6.00) is an orthotropic type and the orthotropy direction is perpendicular to the panel plane , which is an error.

I don´t see a reason to use that type of orthotropy with 0.999998 factor for all stiffness terms , but this is your problem.

Using an isotropic wall or orthotropic with correct orthotropy direction will solve all your problems
