Getting Started

FEAScript platform is a browser-based visual editor that allows you to create simulations by connecting blocks together. These blocks represent different operations and configurations needed for finite element simulations.

To create a simulation:

1. Drag blocks from the toolbox (left panel) into the workspace
2. Connect the blocks in a logical sequence
3. Configure block parameters as needed
4. Click the "Evaluate" button in the Control Panel to run your simulation
5. View the results in the "Solution" tab

You can save your work by clicking "Save Project" in the Control Panel, which will download an XML file. To load a previously saved project, click "Load Project" and select the XML file.

Block Categories

The following block categories are available in the FEAScript platform:

Model Operations

Blocks for creating and solving FEAScript models:

• Create model - Creates a new FEAScript model instance. This should be the first block in your workflow.
• Solve model - Solves the configured model using the selected solver method. Options include:
  • lusolve - Uses LU decomposition for direct solving (faster but requires more memory)
  • jacobi - Uses the iterative Jacobi method (slower but requires less memory)

Solver Configuration

Blocks for configuring the type of physics to be solved:

• Set solver - Sets the solver type to use. Currently available:
  • Solid Heat Transfer - For heat conduction problems

Mesh Configuration

Blocks for defining the computational mesh:

• Import mesh file - Opens a file dialog to import a mesh file (experimental)
• Set 1D mesh - Configures a one-dimensional mesh with options for:
  • Element order (linear or quadratic)
  • Number of elements in X direction
  • Maximum X dimension
• Set 2D mesh - Configures a two-dimensional mesh with options for:
  • Element order (linear or quadratic)
  • Number of elements in X and Y directions
  • Maximum X and Y dimensions

Boundary Conditions

Blocks for defining boundary conditions for the simulation:

• Add constant temperature boundary condition - Applies a fixed temperature to a boundary
  • Requires boundary key (a string identifying the boundary, e.g., "0", "1", "left", "right", etc.) and temperature value
• Add symmetry boundary condition - Applies a zero-flux (symmetry) condition
  • Requires boundary key
• Add convection boundary condition - Applies a convective heat transfer condition
  • Requires boundary key, effective heat transfer coefficient, and external temperature

Postprocessing

Blocks for visualizing and analyzing results:

• Plot results - Visualizes the solution using the specified plot type
  • Currently supports "contour" plot type for 2D results and "line" plot type for 1D results

Basic Blocks

Utility blocks for providing input values:

• Number - Provides a numerical value
• Text - Provides a text string value
