can anyone help me with wind load generation (wind load general, static & dynamic) and assign using staad pro physcial modeler and also for seismic load also. Kindly explain the process briefly

I need to understand how to generate loadings in physcial modeler like wind load & seismic loads. while doing in physical modeler, to apply/assign wind load to the structure I have to create the wind load definition in catalog tab and go to loading tab>load cases and select load type>category (here if after selecting wind general it shows self weight data, should i add/assign 1 on the required direction or just leave it???) and i didn't get the wind static, wind dynamic, seismic definition, seismic H & V general). And Kindly explain what to use and why we use these parameters. 
Thank you
