EMC Studio v8.1 comes with many new features and includes significant enhancements to current functional capabilities. This new release includes extended tools for working with conformal antenna features, special post processing tools for deep analysis of smart entry systems, import of KBL harness data, and more. Also EMC Studio v8.1 introduces new Distributed Calculation Management System. Build-in Queue Manager communicates with calculation server and provides possibility to schedule user tasks and distribute them to different computational resources.

Construction of Antenna Pattern:

- Automatization of antenna pattern pre-processing (reduce pre-processing time from one week up to 2 hours)
- Full automatization of procedure required to generate discrete model for glass surface and antenna pattern (obtain guaranteed result within several minutes)
- Improved handling of glass antenna to assign physical properties (substantial improvement in GUI)

Construction of Antenna Cables:

- Generation of 3D MoM model for wires passing in route tubes

Construction of Antenna Pigtails:

- Automatic generation of wires on defined base points and length

combination of fast calculation techniques (Multi Excitation Solution and Matrix Partitioning Method) for optimization and tuning purposes. Advanced GUI tools give flexible possibility to prepare simulation model and configure calculation tasks.

*Model Partitioning:* model geometry needs to be divided into main (Base Layer) and additional parts (Additional Layers).

*Excitation Sets Definition:* all excitations need to be combined into groups (Excitation Sets).

*Computational Tasks Definition:* after model partitioning and excitation sets definition, all layers and sets are combined into special groups (Tasks) that form the computational tasks and can be executed in user defined sequence.

Very often imported geometry models intersect ground plane. For such cases model adjustment above ground can be done very easily by defining required Z level for ground plane. This way is more flexible than applying transformation operations on imported model. By default, ground plane is placed in z=0. It is possible to shift ground plane along Z axis by defining required Z Level value in Ground Properties dialog.

- 2D and 3D view of impressed current data
- Operations on impressed currents sub-segments (export to file, create new impressed current based on selected sub-segments, create termination nodes, merge impressed currents, etc.)

EMC Studio v7.0 provides improved calculation of stochastic bundles and advanced tools for its analysis. Stochastic analysis method allows characterizing a system of stochastic cable bundle by performing a number of simulations of a given system and applying statistical processing methods to calculated data. Obtained results are visualized as stochasticity map with colors indicating result probability in each map region.
