Hi Abishek,
when you export from Ansys, you need to export it in ASCII format.
Step 1: export the solution data in ASCII format( you need to select ASCII in the export dialogue box)
Step2: export the particle solution. make sure you give different names for solution data and particle data.
step3:you should be getting a file name ,newencas. open the file and remove all the asterisk in the file and save the file.
step: open the .newencas file using Ensight reader in Paraview.
incase you want to open the solution data. open the exported solution data, remove asterisk and last two lines in the file. save it and open in Paraview.
note: export the solutions in Ensight format
