Currently, multiple layers of sedimentary layers are being tested in rivers with ideal square grids.

There is a lack of information on this, so even if an error occurs, it cannot be solved.

The flow model was operated normally, and when the water quality model (Bloom) was set after coupling in the flow model, the model was operated normally.
The output of the result was no problem.

However, when applying multiple layers of sedimentary layers, an error occurs and the model does not rotate.
The inf file is as follows.
1) Bloom test: 50×10.inp -> Normal operation
2) Multi-layer test: 50x10_multilayer.inp -> model error man.

How can I modify the input so that I can be a model?

If you don't mind, I would like you to revise the input and give me an answer.

p.s
1)Currently, I'm running a model on a Linux-based computer through the 7545 version.
2)Send the .inp file of the relevant model found in the forum together.
3)Due to capacity problems, the model result file and the coupling result file are deleted and uploaded.
Coupling made a coupling result file through PLCT.
