Thank you.

File modol of me.

The model you send me is linear:

Sorry.

you please add the same picture.

Thanks.

I do not see any problem with Newton Raphson algorithm.

calculation times:

all cases, Newton Raphson, Sparse Solver - 2227seconds

simple cases set as auxiliary, Newton Raphson, multithreaded solver - 1700seconds - such model here :

thank you very much.
You let me ask one question.
By my modol, then I should choose it is U + or U-?????
To get the correct results.

[Rafal.Gaweda · Accepted solution]

It depends on local Z of panel

in your case U+

Examples:

No support s in UX UY directions.

I suggest you to use Automatic solver - it will report instabilities in model.

[athurD]

Thank you reply.

I selection Automatic solver. File modol run normal.

I show deformation combo1 normal, So why Combo2,3,4,5,6,7 deformation verry max????????/. Please see picture.

It means ADD such supports.

Example below

Thank you verry much.

I do not know to add ux, Uy.

Add it using the tool???

[athurD]

Please guide me App support in UX UY directions same picture RG_Adsk  ???.
I desperately needed for my work.

Thanks.

WHy are you modelling structures if you do not understand this?

[athurD]

Sorry tony.

If you can tell me, I do not know what I asked.
