Melting object

• Parts

  • Elements

  • [x] Leave only LagrangianFluidVMS3D

  • [x] Remove the selector

  • Const law in parts

  • [x] Remove the selector

  • [x] Leave only Material (remove properties) and emissivity and convection coefficient

• Conditions

  • [x] Leave Fixed velocity la base

• Materials

  • [ ] Change Materials and add missing parameters ( @maceligueta )

                    [298.0, 1000000.0],

                    [473.0, 500000.0],
                    [553.0, 8706.0],
                    [613.0, 3716.0],

                    [798.0, 500.0],
                    [1373.0, 500.3]
                ]
            }
    }

Thermic

• Conditions
  • [x] Remove thermal face condition
  • [x] Convert laser into blockdata, but keep print as a process

Writing

• [x] Mdpa only contains:
  • Nodos
  • Elementos
  • Submodelpart de fixed velocity

• [x] Ambient temperature y gravity to json

• Output processes

  • [x] Model part is the main

• [x] Only 1 material file

• [x] Mesh size to json as "mesh_element_size": 0.03

08/11/21 Meeting 08/11/21 notes additions (kernel changes only):

• [ ] Make sure the app reads the materials file and adds all properties to Properties 1
• [ ] Improve the RegenerateMesh function to accept an Id for element properties and another for conditions properties
• [ ] Divide RegenerateMesh is severa subfunctions
• [ ] Migrate all the laser operations to the LaserProcess
• [ ] Set the initial temperature to all the nodes directly from the solver at the beginning of the computation. Environment temperature should be in the json
• [ ] Review the python function cleaning_submpodelparts and check if it must be called at every time step
• [ ] Review the python function filling_submodelparts. Check if we can avod filling the computing_model_part at every time step. Maybe the main_model_part is enough for the fluid purposes. @juliobarna

At this point, the problemtype generates:

• mdpa with nodes, elements and submodelpart for the floor
• project parameters json
• materials file
• laser file
