Hello there, I'm trying to develop a study with the RL-GO solver, so I also need to run a "pre-study" to create the .tr file for the medium. One of the parts in question is made of construction_concrete. In the "pre-study" I'm creating a layered structure of 5mm per side with the following properties: Thickness: 0.1mm (due to WARNING 2757: A triangle is too thick as compared to the lateral dimensions for application of the skin effect approximation) Dielectric material: Construction_concrete_block As the Example H05. Jerusalem_Cross_FSS specifies, I'm including a two dimensions PBC with 5.2mm per side, the operating freq. is 77GHz and running the solver the following WARNING appears: WARNING 49005: Reflection/transmission not defined due to possible grating lobes. I reviewed other similar questions here at the forum (Interpretation of the near field) and one of the alternatives is to move the measurement of the transmission/reflection coeff. to 10 wavelengths, lambda=c/f, 3x10^8/77=3.896mm. If I request the transmission/reflection coeff. at: X: 4mm Y: 0mm Z: 0mm the WARNING still appearing. I think using near field request for "Calculate only the scattered part of the field" is not the more appropriate alternative since my full model intended to run with RL-GO is in meters. Should I change something on the study definition? Or this is something I can take as an "acceptable" WARNING? Should I change the solver for the full model? Thanks for your support on this, -David
Hi, I m working on crash simulation which involves a reinforced concrete cement block at the foundation. Currently I have made a solid block for representing concrete and removed tmr rods solid part fomr it. Is this is the methodology or any other to be used? In case of any reference file kindly share I have attached the image of reinforced rods structure over which concrete will be poured. Thank you
