Hi,

I have many warnings but the calculation (static analysis) runs.
Do you think that these warnings affect results ?
How can I solve this ?
Please find below the errors.

    Benoit,

    These warnings are about the accuracy of the results, you will have to decide if you can ignore them !

    The weighing factor as you may know is to vary the distribution of the load,

    The weighing factor must be adjusted until you get the right results, you may have to test this on a simple model until you get the values you want i.e until the rbe3 represents the real component accurately,

    more specifically to your case it looks like there are weighing factors applied to rotational dof along with your translational dof, this is not advised generally, What is the reason for using this? can you describe the model etc ?

    The second warning is as it says because you have only two independent grids, you may have to rethink that as well.
