Altair S-Calc 2026.0

Altair S-Calc

 

Altair S-Calc is a powerful, specialized section property calculator engineered for professionals who work with complex geometries and multi-material sections. Unlike standard section property tools limited to simple shapes, S-Calc handles the most challenging configurations—built-up sections, cold-formed profiles, bridge girders, reinforced concrete shapes, and arbitrary user-defined polygons. Version 2026.0 continues Altair’s commitment to engineering precision and productivity, offering multiple calculation methods (database values, closed-form solutions, polygon algorithms, and FEA), seamless BIM and DXF import, and an extensive library of over 70 parametric shapes. For engineers who need accurate section properties for analysis, design, and code compliance, S-Calc delivers the precision and flexibility that complex engineering demands.
