Go to Common Settings for Probes for information about the Variable name, Source Selection, Expression, and Table and Window Settings sections.
|
Select an option from the Type list: Average (the default), Maximum, Minimum, or Integral depending on what type of value takes over the domain, boundary, or edge that you want the probe to compute and output. If needed, enter or edit a name for the Probe variable. The defaults are dom1 for a Domain Probe, bnd1 for a Boundary Probe, and edge1 for an Edge Probe.
If you have selected Average or Integral from the Type list, the Integration Settings section contains the following settings:
|
•
|
From the Method list, select Integration (the default) or Summation. Only reaction forces use the summation method.
|
|
•
|
If desired, for the Integration method only, enter an integer value in the Integration order field (default: 4).
|
If you have selected Maximum or Minimum from the Type list, the Integration Settings section contains an Element refinement field, where you can enter the element refinement (number of partitions of an element edge) to control the accuracy of the maximum or minimum value (default value: 4).
When working with multiple frames for any type of probe, you can also select a Frame — Spatial, Material, Geometry, or Mesh — followed by the coordinate names: typically (x, y, z) or (X, Y, Z) depending on the physics in 3D, for the volume element to be used in the integration.
If the component’s geometry is a 1D or 2D axisymmetric geometry, and the probe Type setting is set to Average or Integral, select the Compute surface integral (for Domain Probe nodes in 1D axial symmetry and Boundary Probe nodes in 2D axial symmetry) or Compute volume integral (Domain Probe nodes in 2D axial symmetry) check box to compute an average or integral that takes the axial symmetry into account. COMSOL multiplies the expression (integrand) with 2*pi*r or pi*r prior to integration to compute the corresponding surface or volume integral.
