Hydrodynamic module for aquaculture structures

aster_seacondition_module

For wave models Straight Cylinder with Sinkers

This is a document for a fish cage that similar to the simulations in Section 4.3.4 from this paper, but with a bottom netting.

Cheng, H., Li, L., Aarsæther, K.G. and Ong, M.C., 2020. Typical hydrodynamic models for aquaculture nets: A comparative study under pure current conditions. Aquacultural Engineering, 90, p.102070.

The fish cage in still water

File structures:

• asterinput
  • module
  • asterinput1.py --> calculation script
  • asterinput2.py --> calculation script
  • ASTERRUN.export --> submit job for code aster

• clean.sh --> clean the generated files

• run.sh --> start the simulation

• setting.py

Work environments

Required packages:

• python 3.6 (or higher)

• Numpy 1.20 (or higher)

• Code_aster 14.6 (or higher stable version)

  Please check if as_run located at the following default installation path:

  /opt/aster146/bin/as_run

  If not, you need to change Line 16 in run.sh and Line 2 in ASTERRUN.export according to your environments.

• salome_meca 2019.0.3

  Please check if salome located at the following default installation path:

  Default installation path:

  /opt/salome_meca/appli_V2019.0.3_universal/salome

  If not, you need to change Line 2 in run.sh according to your environments.

How to start the job

Easy and Fun

1. Open a terminal and change the directory to the Example

2. Type the command:

   sh run.sh

3. Wait until the job finish. If it shows exit_code=0 at the end, it means the simulation finish without any error.
