FRONTAL ERROR

Hi guys,

 

Getting an error "Execution problem 3324".  I know this is "Too many prev. front - multifrontal solver".

 

Question:

How the f%#k do I get rid of this error!!!!   I tried running skyline, but very slow. 

The model ran 10 times OK, then gave the error.  Is there some registry I need to clean out?  I close Robot etc but still get the error. 

 

Any help welcome!

 

Tony

What about multithreaded or iterative solvers?

(Recommended settings for iterative solver in case of big models: ICCF+no_multilevel+1/2memory)

Hi Rafal,

 

No it's not a big model, and I'm running a pretty decent machine (well they wont pay more for a better one anyway :smileymad: )

I have 12 Gb ram and good spec processor etc. 

 

Multithread works ok.  Actually I opened the file in recovery and then it works again.  Was just a strange error so it suprised me.
