CST2013: 2D and 3D Field Results / - Mix 3D fields

Post Processing: Result TemplatesTemplate Based Post Processing

This template offers a calculator for 3D Fields, performing numerical operations such as "add", "subtract", "cross product". The result of the operation is a new 3D Field, which will be written in 2D/3D Result Tree. The location in the tree is specified in the dialogue (default name is Combine). The newly created 3D result can be referred in other templates for 1D Plotting, curve-, face- or volume Integration. (Preloaded Result Templates)

In CST STUDIO all 3D results are handled as Result3D Object (please check for Result3D Object in the VBA Online Help).  

This object offers access and manipulation functions to 3D results. A Result3D object may either contain a vector field or scalar field. If a scalar field is represented by this object, its values are treated to be the x-components of a vector field, while all other components are not available.

Please keep in mind: the template does not check if the requested operation generates a physical meaningful result. (e.g. simply adding the electric and magnetic field together does NOT create a physical meaningful result but is still possible).

All Result3D Objects in CST Studio have certain properties like a frequency and a field type. Frequency and field types are used for plotting purposes.

The newly created 3D Field will have the same frequency as source field one. The result field will be plotted in the units of the field type. Dynamic fields have real and complex components, static field have real part components only.

Action

The following actions are possible:

"Add Fields"

This operation adds the selected source fields. If requested, the template will use conjugate complex of the source fields and it will scale the source fields with the user given factor before the fields are added.

"Subtract Fields"

This operation subtracts the selected source field 2 from field 1. If requested, the template will use conjugate complex of the source fields and it will scale the source fields with the user given factor before the fields are subtracted

"Cross Product"

This operation calculated the cross product field 1 x field 2. If requested, the template will use conjugate complex if the source fields and it will scale the  fields with the user given factor before cross product is calculated.  

Example: The Poynting vector of the fields can be found by calculation the cross product of the electric field and the conjugate complex of the magnetic field.  

"Square Source Field 1"

With this operation the square of source field 1 is calculated. All components of the source field (real and imaginary part  of the x, y, z component of the field) are squared and added together. The result field will always be a scalar field. If requested, the template will scale the source field before the operation.  

Example: The Electric Energy Density (peak) can be calculated by using the square of the electric field multiplied  by the permittivity of vacuum 8.854e-12  F/m and dividing the result by 2.

"Scale Source Field 1"

This operation scales the source field one with the user given factor.

"Extract X-Component"

"Extract Y-Component"

"Extract Z-Component"

This operation returns a complex scalar field which contains the complex value for the  x/y/z Component of the source field.

"Extract Amplitude Field 1"

This operation returns a field with the Amplitude of the x, y and z component of the source field.

Example: The Plot options of CST MWS allow the user to plot the amplitude of the time dependent fields. Since this is only a plot view, no further post processing can be done.

The "Extract Amplitude" operation generates a new Result3D object which is identical to the plot view and which might be used for further post processing steps.    

Plot Type

The user can assign any of the following fieldplot  types to the result field.

"dynamic e-field"  electric vector field from a dynamic simulation.

"dynamic d-field"  electric flux density vector field form a dynamic simulation.

"dynamic h-field"  magnetic vector field from a dynamic simulation.

"dynamic b-field"  magnetic flux density vector field form a dynamic simulation.

"dynamic powerflow"  vector field of the calculated Poynting vectors.

"dynamic current"  vector field of the current density from a dynamic simulation.

"dynamic e-energy"  scalar field of the electric energy density.

"dynamic h-energy"  scalar field of the magnetic energy density.

"dynamic loss density"  scalar field of the loss density, caused by a conductivity.

"dynamic sar" scalar field of a sar simulation.

"static e-field" electric vector field from a static simulation.

"static d-field" electric flux density vector field form a static simulation.

"static h-field" magnetic vector field from a dynamic simulation.

"static b-field" magnetic flux density vector field form a static simulation.

"static current" vector field of the current density from a static simulation.

"static el-potential" scalar field of electric potentials.

OK

This button completes the setup of the template. The new entry will be added to the list of templates which are executed automatically after each run. The default name of the template is set according to the settings, as long the name has not been changed manually.

Cancel

Aborts the setup of the template and closes this dialog box without performing any further action.
