In creo simulation after running analysis we got .mcd file, so need details for same

Hi,

We have run creo-simulation analysis and found that in directory one .mcd file got generated. We tried to open it in mathcad 15 and mathcad prime 4.0 but it not got open. So anyone having idea, what was there any that file and how we can open this file. (analysis run in creo3.0 M120).

Thanks,
