EMPro Environment Overview
Geometry modeling
– Arbitrary 3D structures can be created
using the powerful EMPro drawing
environment.
– Alternatively, structures can be
imported from other CAD environments.
Supported file formats include: ACIS,
IGES, DXF, STEP, ProE, SolidWorks,
ODB++ and others.
– Material properties are assigned to
imported or drawn 3D objects using a
simple drag-and-drop from an extensive
material database onto the 3D objects.
Once assigned, the material properties
are memorized for subsequent CAD
imports, enabling even faster simulation
setup.

can be placed on the object and the
source impedance defined.
– Additionally, for FDTD simulations,
external plane wave and Gaussian
beam sources can be set up. Sensors
are also set up to detect near-field
and far-field voltages, currents and
field quantities. Special SAR and HAC
sensors can be added for compliance
testing.
– For FEM simulations, waveguide ports
can be set up.
Mesh setup
– For FDTD simulations, a
rectangular mesh is generated based
on the shapes of the objects. Initial

mesh is automatically generated to
optimize accuracy and simulation time.
Fixed point meshing automatically
aligns the mesh with object boundaries.
Users can tune the mesh to make
further trade-offs between accuracy
and speed.
– In a similar fashion, a tetrahedral mesh
is generated for FEM simulations. The
mesh is optimized for speed/accuracy
through a process of automatic
adaptive refinement.
