Cannot find jacobian array file

Recommended Posts

Often when I initiate a PEST run with SVD-assist and NOPTMAX = -2 or -1 the process ends with the message "cannot find Jacobian array file".

The process starts with a calculation of the Jacobian matrix:

But ends like this:

It always works when I run the model without pilot points. A forward run with the pilot points also works.

I have managed to run both a parameter estimation and NSCM with SVD-assists before with the same model constraints but when experience this problem when I attempt to make changes in the model. 

Ideas on how to solve this issue?

Hi, 

I still have the same problem but with another model this time. The problem happens when I add additional parameters for the PEST-estimation. No difference between a PEST calibration with SVD or SVD-assist.  Any ideas on how to solve this issue would be appreciated. I run GMS 10.3.5.
