Help the "STOP: Numerical Instability" Error

[Yoon Hee Park]

Dear all,

I'm working on Cone Calorimeter Test for composite materials using Pyrosim.

But I have some problem, So I hope to help me.

My first error is  "WARNING: MATL Jute fiber, REAC 1. No product yields (NUs) set" and second is "STOP: Numerical Instability".

The structure of the composite materials I used is 2 sheet of Jute fiber/2 sheet of Carbon fiber/2 sheet of Jute fiber and used Epoxy Resin.

Modeling runs for a very short time and stops.

I'll attach the Pyrosim file I modelled and Please help me.
