RE: Problem to find equilibrium under variable discharge

Hi,

The space marching method is something for Liselot to answer... I will reach her. The crash occurs because the size of `Mak` does not match with the number of flownodes (`dx`) and the number of effective size fractions (`nef`). There must be something murky there. Maybe you could stop in debug mode and check what are the dimensions of `Mak`.

Problem to find equilibrium under variable discharge

Hi,
I have the following question-

1. I have been trying to calculate using the space marching method (initype=52) for unisize sediment single branch problem. For initype 2, the code runs smoothly but with 52 it crashes with the following set of messages-

***
Number of elements must not change. Use [] as one of the size inputs to automatically calculate the appropriate size for that dimension. in sediment_transport, at line 145
The parents are:
1)    march_step_uni, at line 62
2)    ini_equi, at line 130
3)    initial_condition_construction, at line 259
4)    condition_construction, at line 85
5)    ELV, at line 106
6)    run_ELV, at line 53
7)    oh_ELV_please_run, at line 157
8)    main_run_single, at line 37

***

I tried to follow the error code, but could not solve it. What is the problem in this case? I have attached the input file.

Thanks in advance.
Best wishes,
