problem model muletto ansys

[shinobi9]

Hello, everyone. .I am new to the forum and an ansys about 10 giirni!for an exam I have to make a model of a forklifter.When the static structural solution gives me a mistake that I don't understand"a large negative pivot value cp has been ancountered etc...." and concludes saying that it could be due to a bad choice of the dependence of a property from the temperature...but I am doing a structural analysis I don't understand the link between these two things...https://www.dropbox.com/s/1s3vlm37bzcendw/finish.txt?dl=0If you want to try to see directly you would do me a favor..in such case you should put 2 constraints (two inches in the 2 final knots of the 2 more external guides) and 2 forces on the tips of the forks (negative in the direction y) maybe you understand where I wrong!thanks anyway!

error in the resolution. try to fall resolution method.
ps controls the constraints

Thank you so much for the answer! what do you mean by resolution? I don't understand.. As for the constraints, did you notice any mistakes? Thank you.

I didn't really open the model.
when you go to solve the structure you can choose from different resolution methods (in practice you are resolving a matrical problem), I do not remember precisely the section of the dedicated program.
