Quartus Prime 16.1 - Timing simulation error .sdf file

Hi,

I am using the university VWF to perform a functional and timing simulations.

I encountered two problems, one i managed to solve.

1. the simulator for some reason expects the simulation .wvf file to have the name Waveform.vwf, otherwise you would have to manually change the name from the simulation settings. Is there some workaround for this? (This I solved by changing the name manually, but it's a tedious task)

2. the next error was in the timing simulation which didn't work at all. 

# ** Error (suppressible): (vsim-SDF-3196) Failed to find SDF file "light_vhd.sdo".
# vsim -novopt -c -t 1ps -sdfmax light_vhd_vec_tst/i1=light_vhd.sdo -L cyclonev -L altera -L altera_mf -L 220model -L sgate -L altera_lnsim work.light_vhd_vec_tst 
# Error loading design

I tried to search the project folder for .sdo/.sdf files but nothing came up.
