Numerical Sensitivity check - 03/19/09 02:15 AM

Hi to all,

Here i attach one of my CAESAR error report. I do not know how to solve this problem? If i introduce friction with Gap it gives in core solver problem? but i did not introduce friction, still it is coming like that.

So, Please Help me to resolve this type of problem?


Thank You.

What "In-Core Solver" problem? If this is a "convergence" issue, search for the word "convergence".

it is not a convergence problem. whenever i press CAESAR run button it shows this pop ups window. after i accept this pop ups it shows the result Box.

even though i did not introduce any constraints.

Thanks.

SHR solve my problem.

thanks Richard Ay and SHR.

That "pop-up" is displayed if you set the Configuration option to perform the "numerical sensitivity check". If you see all zero values, you have no problem. If the values reported approach 1, your model is unstable.

If you don't want to see this "pop-up", change the Configuration option.
