Hi junaed.buet,

The case you explained will not happen generally. 

But from the information, you provided below are the observations and suggestions.

1) Looks like there are some global variables($Lend...) defined. Please check if any time-dependent parameters are defined for them.

2) Is the speed constant or is there any variable affecting the speed?

Regards,

Navya
