Hello everyone,

In the calculation case of gas transport in a three-dimensional pipeline, laminar flow transient calculation is used. The time step is about 100,000 steps, but calculation errors will occur to a certain extent. I tried to adjust the time step and some basic settings, but the same error occurs every time, and the time step when the error occurs is different each time.
Any suggestion would be helpful.
Thank you!

"Error: out of Scheme heap space
Rerun with -h flag set greater than current value of -h100000"
