Description of the nodes

Parse Materials:

Lista de materiales. Que usar de nombres? Assign materials to modelpart Parse Modelpart file: MP settings Parse materials file: Materials settings, lista de materiales

from MP settings creates list of materials as inputs. Materials are connected to submp

Project parameters

Required inputs

solver processes input processes boundary conditions processes output

Optional inputs (have sensitive defaults) problem name parallel type echo level start time end time

Output: ProjectParameters object, that can be input for “Export case files”: need to pass data to get materials and model file. “JSON Viewer”: actually, output is only json, so this is the only module available so far

WIP: Project parameters module: reset input when connections change

Solvers

Solvers require data from other modules “Parse modelparts file”, which returns Model parts settings (a json block with info about the model file name and type), and a list of submodelparts classified as volumetric, skin and non-skin

• Linear solvers
• Time stepping: Module that generate time stepping schemes
• Formulation: Module with options and setting for specific formulation of the solver
• Fluid Solver Required input Model part settings Volume submodelpart Skin submodelpart Non-skin submodelparts Linear solvers Materials Time stepping Formulation

Structural Mechanics solver Time Time Stepping automatic_time_step: true / false time_step: 0.1 "time_step_table": [ [ 0.00, 0.01 ], [ 0.02, 0.01 ], [ 0.03, 0.10 ], [ 1.00, 0.10 ] ] } WIP: Implement internal logic. Particularly, the time step table. Find a function that processes time in Kratos. Formulation Available formulations: fractional step, monolithic Optional input: element orthogonal subscale dynamic tau Output: Formulation object, to be connected to Solver module Linear solvers Setting for the AMGCL linear solver
