I have problems in setting Assimilation Module

[kimyy308@snu.ac.kr]

Hello

I want to run MOHID Hydrodynamic Model.

I think Some problems in setting the Assimilation Module.

but I can't find problems' location.

I tried to Assimilate velocity U in open boundary point.

however results of velocity U are all zero value.

I upload all of model setting file(4th simulation have this problem) and write important part in each module


please help me.

I corrected coef file and add 'BRVELOCITY = 1' option into Hydrodynamic module.

assimilation module runned, but I got another error.


-----
FATAL; INTERNAL; HydroPropAssimilationVelocity - Hydrodynamic - ERR40.

Program stop anormaly. See Log file.
-----

I think This error should come subroutine GetAssimiliationCoef.

in this subroutine, 3d variable get file's coefficient.

if coefficient is 2d variale, Module give me an error message(ERR40).

but My model is 2D model, So coef must be 2D variable.

I correct DIMENSION value in ASSIMILATION Module to 3,

Model give this error message.
