ALEXANDRIA, Va., June 2 -- United States Patent no. 12,645,857, issued on June 2, was assigned to ANSYS INC. (Canonsburg, Pa.).

"Systems and methods for blending AC and DC models for electromagnetic simulation" was invented by Werner Thiel (Sewickley, Pa.).

According to the abstract* released by the U.S. Patent & Trademark Office: "Systems and methods are provided for A computer-implemented method for simulating behavior of an electrical circuit across a range of frequencies from 0 to fmax. A base function is determined that outputs magnitudes across the range of frequencies. A correction function is determined that outputs magnitudes across the range of frequencies. The base function is combined with the correction function to generate a...
