MeshCfg URN definition of meshes

The handling of mesh configuration is done by d_mesh MeshCfg. The convention is that the mesh URN is of the form Mesh:Case:NL. Thus d_hbm(0D):DofSet:0Dm1t says that

• the d_hbm('MeshOD') command is called to obtain the mesh
• the d_hbm('CaseDofSet') command is called to set case information (loads, sensors, ...)
• the d_hbm('NL0Dm1t') command is called to set non-linearity information. Here ODm1t refers to a specific material.

SimuCfg URN definition of time experiment

The handling of time simulation configuration is done by d_fetime SimuCfg. Different conventions are being developed for different types of experiments.

SteppedSine{.5,1,10}:C0{0,15}:C1{2.5,10} is used to characterize stepped sine tests. The URN is split as follows

• SteppedSine{.5,1,10} gives the target frequencies in Hz.
• C0{0,15} gives the harmonic 0 or static offset. xxx scaling convention
• C1{2.5,10} gives the first harmonic or time signal of the form cos(ω t)
