Results and Display

There are 3 types of simulation results and associated displaying types available with Femtet.

Types	Notes
Field	Fields are the physical values which are distributed over the simulation space. Therefore, the graphical representation is well suited for them. The electric field in electric field analysis, the temperature in thermal analysis and the displacement in stress analysis etc are the examples of fields.
Result Table	Some characteristics are summarized in the numerical table. Examples are the capacitance in electric analysis, the inductance in magnetic analysis, the characteristic impedance in waveguide analysis, and the resonant frequency in resonant analysis. Just the numerical summary is good enough for them in most cases.
Characteristics by Charts	Some characteristics can be shown by charts For examples, the frequency plots are quite common for S-parameters, impedances and admittances, whereas the polar coordinates are well suited to show the directivity.

The available types of results and display depend on the solver. See [Displayable Results for Each Analysis].

How to Display Fields

On the [Results] tab, go to ,
click [Field] .The screen will change to Results Window, and the field will be displayed.

Alternatively, double click the Field item on Project Tree.

Select the result field of your interest on the [Results] tab.

The detail about the [Results] tab is explained at [Display].

You can freely edit or add fields. Refer to [Select, Edit, or Add Fields].

You can select how to display from the 11 types listed below.

Display Types	Notes
Mesh Diagram	Shows the meshes. They are triangular in 2D analysis and tetrahedrons in 3D analysis.
Displacement Diagram	Shows the displacement in various scales.
Gradation Contour	Shows the field with contours by color progression.
Isoline Contour	Shows the field with contours of isolines.
Isosurface Contour	Shows the field with contours of isosurfaces.
Surface Vector	Shows the surface field with arrows representing the magnitude and the direction.
Element Vector	Shows the field with arrows representing the magnitude and the direction.
Cross Section	Shows the field of specified cross sections.
Boundary Conditions	Shows the boundary conditions.
Charts	Shows the field values between the 2 specified points.
Show Maximum and Minimum	Shows the magnitudes and locations of maximum and minimum field values.
Results at Specified Coordinates	Shows the field values at the specified coordinates on the output window.

* More meshes means better calculation accuracy but longer time for graphics display. See [How to Speed up the Results Display].

* [Graphics Setup] describes how to set up the mesh diagrams, contours and vector diagrams.

Results Display Setting

The setting for the results display can be registered for later reference.

Extract Results

The maximum and minimum values of the fields, the values at the specified coordinates, and the calculated values are extracted from the specified results.

See Extract Results for the details.

How to Show Result Table

On the [Results] tab, go to , click [Table] .

Alternatively, double click the Table item on Project Tree.

See [Result table] for the details.

How to Display Charts

On the [Results] tab, go to , click [Chart] . There are 4 kinds of characteristics displayable on chart.

Alternatively, double click the Chart item on Project Tree.

Characteristics to Display	Notes
S/Y/Z-Parameters	S(Y)-Parameters acquired by electromagnetic analysis or harmonic piezoelectric analysis can be plotted over the frequency.
S/Y/Z Matrix	S-Parameters and impedances acquired by electromagnetic analysis or harmonic piezoelectric analysis can be plotted over the frequency.
Impedance (Piezo-Resonance)	The frequency resopnse of the impedance acquired by piezoelectric analysis (resonant analysis) can be shown .
Directivity	The far-field directivity of a model with open boundary in the harmonic electromagnetic analysis The directivity of sound pressure in acoustic analysis The directivity of magnetic field in magnetostatic analysis. The above can be plotted on the X-Y or polar coordinates.
Dispersion Curve	The frequency response (dispersion curve) of the phase constant at a port in the harmonic electromagnetic analysis can be plotted. - The dispersion curve is not available for the results in electromagnetic (waveguide) analysis.
Piezoelectric Current	The frequency response of the current amplitude can be plotted.
Piezoelectric Charge	The frequency response of the charge amplitude can be plotted.
Electric Potential of Piezoelectric Floating Electrode	The frequency response of the amplitude of the electric potential of floating electrode can be plotted.
Mode Information	In the electromagnetic-harmonic analysis, the propagation constant, and the loss of each body are displayed.
