It happens all the time. Too often we still see companies that trust on simulations being performed with a solid-mesh, while the geometry is thin walled, like with sheet-metal, extruded parts or plastic parts. If you ask the people why they didn’t use a shell mesh, most of the time they will tell you it will take too much time to generate a mid-surface shell model, or they think it is not feasible capturing the necessary detail in the analysis, so they decided to just ignore the rules.

Below we have listed why creating a mid-surface shell model is still favourable.
