SENSE utilizes cutting-edge algorithms built on the basis of BEM method, which provided accurate results in much shorter simulation time with respect to competition. Moreover, accuracy is ensured through the detailed mesh investigation that is made for the ready-to-use patterns of SENSE’s library, or by using a smart Adaptive Mesh Refinement algorithm for the imported custom patterns.

Simulation results are validated both against experimental results of touch panels and values obtained from an analytical solution (for example capacitance between concentric spheres).

SENSE doesn’t use empirical equations to provide results. It uses the Boundary Element Method which is accelerated by the Fast Multipole Method, thus producing a fast iterative solver of linear time and memory complexity.

Simulation time depends on, besides the shape and dimensions of the model, the number of pointer positions that are selected in parametric analysis, and of course the CPU cores that are used. For example, when using 256 CPU cores, a parametric simulation of a typical double layer diamond pattern including 16 different pointer positions is solved in about 6 minutes.
