Plotting & exporting calculation results in PLAXIS Output: Embedded Beams (Ux, Uy, Utot, M2D, Q2D, SPUx, Nx2D).

1️⃣ Objective: Plot & Export Embedded Beam Results (Single Phase)

This helper tool shows how to automatically generate and export result plots for all embedded beam elements in a selected calculation phase.

Supported result types
  • Ux, Uy, Utot (displacements)
  • M2D (bending moment)
  • Q2D (shear force)
  • Nx2D (axial force)

Python is case-sensitive (so yes… Nx2D is not the same as nx2d).

2️⃣ Step 1: Define Output Directory & Access Embedded Beams

Set where images will be saved, and retrieve all embedded beam objects from Output.

folderpath = r"C:\Users\username\Desktop\Plaxis_playground\plotting\\"  # use your own path
embedded_beams = g_o.EmbeddedBeams

Exports are written directly to disk. If the folder does not exist, export will fail.

3️⃣ Step 2: Select & Activate the Calculation Phase

Choose the phase you want to plot and make sure Output is set to that phase.

phase = g_o.Phase_10
# To process all phases, use: phases = g_o.Phases

# Activate the selected phase in the Output interface
g_i.view(phase)                    # Opens a plot window for the selected phase (default: deformed mesh)
g_o.Plots[-1].Phase = phase        # Assigns the selected phase to the current plot object

If you prefer a silent/batch workflow, you can omit g_i.view(phase) and just set the plot phase, but some setups behave more predictably after opening Output at least once.

4️⃣ Step 3: Loop Through Embedded Beams & Export Plots

Iterate all embedded beams, create a structure plot for each element, set the desired result type, then export the plot image with a consistent naming scheme.

Example: export axial force (Nx2D)
for index, beam in enumerate(embedded_beams):

    # Create a structure plot for the current embedded beam
    g_o.structureplot(beam)

    # Set the result type to axial force (Nx2D)
    g_o.Plots[-1].ResultType = g_o.ResultTypes.EmbeddedBeam.Nx2D

    filename_str = "beam_" + str(index)
    file_name = f"{folderpath}{filename_str}.png"

    g_o.Plots[-1].export(file_name)
Small upgrade

For reporting, you can add ProjectDescription, set legend autoscale, or export at a fixed resolution (e.g. 1920 × 1080) if your API version supports width/height on export().

5️⃣ Result Types (EmbeddedBeam)

To discover what result types are available under ResultTypes.EmbeddedBeam, list attributes:

eb_types = g_o.ResultTypes.EmbeddedBeam
print(dir(eb_types))

for name in dir(eb_types):
    if not name.startswith('_'):
        print(name)

Your exact list depends on PLAXIS version, model features, and what is enabled in Output.

6️⃣ Multi-phase Batch Pattern

To process multiple phases, wrap the beam loop inside an outer phase loop. Keep your naming tidy, or you’ll end up with a folder that looks like a crime scene.

phases = [g_o.Phase_1, g_o.Phase_2, g_o.Phase_3]  # or: phases = g_o.Phases

for phase in phases:
    g_o.Plots[-1].Phase = phase

    for index, beam in enumerate(g_o.EmbeddedBeams):
        g_o.structureplot(beam)
        g_o.Plots[-1].ResultType = g_o.ResultTypes.EmbeddedBeam.Nx2D

        file_name = f"{folderpath}P{phase.Identification}_beam_{index}_Nx2D.png"
        g_o.Plots[-1].export(file_name)

If phase.Identification is not available in your API, replace it with phase.Name (sanitise the string), or use your own label map.

7️⃣ Notes & Best Practices

  • Refer to Helper Tool 1 for “Deformed Mesh” and general plot formatting patterns (legend autoscale, description, zoom, etc.).
  • Batch exporting across many phases can produce a lot of images — plan an output naming/template strategy.
  • If you need consistent framing, use plot.zoom(...) (by object or coordinates) before exporting.
  • When unsure what a plot supports: dir(plot), help(plot), or plot.echo().
Next-step idea

Turn the export routine into a function: input (phase list, result list, beam list) → output (clean, repeatable figure packs).
