I have been trying to optimize the geometry of a copper based metal halide perovskite. I opened the cif file using BURAI GUI and generated the vc-relax input file. I have increased the steps to be 100 but it's not converging either. should I increase it more or making converging not necessary or change the geometry? I'm using 222 geometry and the structure is basically 0-D. I am attaching my input file and a photo of the structure
