Hello,
I'm encountering a MassBalanceError while using ITZI and I'm seeking guidance on parameter adjustment. According to the documentation (since version 25.7), when volume error exceeds max_error, there are two main approaches to control it:
Reducing the time-step by adjusting the CFL parameter
Setting a maximum value for the time-step using dtmax
My questions are:
1、For the CFL parameter: should I decrease or increase its value to resolve mass balance issues?
2、For dtmax: what's the recommended adjustment strategy for this parameter?
Are there any general guidelines or best practices for tuning these parameters to achieve better mass conservation?
I'd appreciate any insights or recommendations on how to properly adjust these parameters to eliminate the MassBalanceError.
Thank you for your help!
