  1. I've found the problem, in the import dialog the "line strings" must be checked... I've updated to 1.5 release Thanks
  2. Hi I updated from 3.1.2.1 to 3.1.4.2 version of Pumpsim, when i try to use the "Convert centreline" tool it does not work. I´m gonna downgrade to 3.1.2.1 version so i can use the tool. You should really improve PUMPSIM, it doesn´t have importante changes compared to VENTSIM.
  3. My question Is about the NPSHa, because PUMPSIM does not consider the atmospheric pressure in that calculation... It's that correct? Regards
  4. Hi I need your support, We have updated one net license recently but the problema is as follow: The network license only Works with the versión 2, when update the pumpsim to versión 3 the network license is not working. Which is the problem? Maybe the license server versión? Regards
  5. How can i simulate air expulsion valves ? regards TRAZO SANTA ANA NOCHE BUENA-2.psm
  6. Meanwhile i´ll manage the pump as fixed flow... regards
  7. WHEN I TRY TO USE A PDP, THE SOFTWARE WARNINGS AS INVALID PUMP CURVE, AND THE PUMP RUNNING APPEARS AS NEGATED
  8. I change the diameter only at the final lenght, and i know about the pressure increment. Can you tell me how to input a positive displacement pump because there are not curves? Share me a sample file Thanks a lot. I appreciate your support
  9. I was analizing the sample before your answer and you've right. I Solved this problem reducing the diameter as you recommend. What I undestand Is the pressure Is lower than the friction losses ir pipe, then the balance result a negative value, correct me if I am wrong please. Regards
  10. I have another example: Length: 4020 meters Pump: Fixed flow 5.63 l/s 89.2GPM; 350RPM FMC POSITIVE DISPLACEMENT Pipe diameter 3" Problem: Cavitation and negative pressure at from 3342.8 meters to end Whats wrong in the model, IS IT BECAUSE OF THE IRREGULAR PATH????? Thanks Trazo_Linea SE-EW 3d.psm
  11. I dont know why pumpsim display negative pressure at the end of the pipe, it must to ve zero. regards 3d_tuberia SIMPLIFICDA.psm
  12. I ´ve found the problem When I try to open the file from explorer the error appears, if i open the file from the program it works. It happens only with this file... Fix this in the next update...
  13. I´ve been working with a simulation, I exit pumpsim but when i try to open the file again i could not do it, the file is corrupted . Can you do something with the file....? SIMULACION CARG 34 SOLO POR RAMPA.psm
  14. Another question, is the result the increment of pressure in the pipe ?
  15. Can you explain me about the value "time" , the other values are from the model... Regards
  16. ¿Is there any way of simulate to obtain a value of pressure caused by water hammer? I need this for the design of shock absorver system regards
