Side by side FEM 3-D magnetic field comparison using ANSYS Maxwell and Surfer Voxler to simulate BIM EMF Modeling of unshielded and shielded MER with 75% energized transformers, network protectors, secondary feeders, switchgears, and distribution panels. Constructing electrical distribution model in ANSYS Maxwell, generating 3D simulation of 60 Hz magnetic field model, importing Maxwell 3-D with Revit/Navisworks building simulation models into Voxler to generate 3-D animation requires weeks of computational and programming time. Although the unshielded and shielded FEM 3-D animation looks impressive it is labor intensive to modify and implement small electrical and building design changes into the large and complex BIM model and re-simulate to generate another 3-D animation to evaluate EMI mpact.
Expensive 3-D animation with limited useful engineering value (looks great if you have the resources to invest). Recommend practical and cost-effective 2-D FEM unshielded and shielded simulation slices at various elevations and views (i.e., plane view, elevation view, etc.) to show 60 Hz magnetic field levels and predicted shielding attenuation within protected areas as shown in the next simulation: AC ELF Magnetic Shield Project –First Floor Office Area, NYC, NY
