  Initial Request
----------------------------------------------------------------

Hello,

I have started learning MET and finish all the steps of MET on-line  
tutorial until MODE Tool. While I am trying to run MODE tool I get the  
following error message: I have look through the MET archive and find  
that someone also posted same problem on April 2011 and a series of  
discussion took place with no end solution. Could anybody please tell  
me how to solve the problem.

Randy,

Can you please take a look at this user's MET help question?  I think
it is a situation that we have seen before, right?
 Basically there is a numerical problem with some compilers as MET is
trying to build the convex hull of an object in
the tutorial data that we distribute.  I don't remember if or how we
were able to resolve this problem.

Thanks,

Paul

Kamal,

Can you please send me information about the compiler and operating
system that you are running MODE on?  We have seen
this behavior before from MODE, but we do not know what causes it.
Please try to run MODE on some other test data that
is not part of the tutorial data sample and, if the same error occurs,
please send us the test data.  I'm sorry I don't
have a better answer for you at this time.

Paul
