Melting object

• Parts

  • Elements

  • Leave only LagrangianFluidVMS3D

  • Remove the selector

  • Const law in parts

  • Remove the selector

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

• Conditions

  • Leave Fixed velocity la base

• Materials

  • Change Materials and add missing parameters ( @maceligueta )

Thermic

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

Writing

• Mdpa only contains:

  • Nodos
  • Elementos
  • Submodelpart de fixed velocity

• Ambient temperature y gravity to json

• Output processes

  • Model part is the main

• Only 1 material file

• 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.

At this point, the problemtype generates:

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