MemberThe example that you are using is very old. Use this, is very similar but adapted to the latest version of the code. Take into account that it is an example and it does not represent a real engine.
Regarding to the discontinuity detected it does not exist. The angle step for the instantaneous results can be modified. “Right click on EJEC -> Mean and instantaneous results”. The problem that you have detect is the 2 degrees between the last data printed in the cycle 5 and the first data of the cycle 6. The difference seems very high due to the high slope of the parameter that you have represented.
MemberCon respecto a las modificaciones que has hecho a mi no me funciona bien lo de seleccionar el directorio de trabajo.
MemberModificaciones propuestas en lo que llamas Library apication
Ves pensando como hacer estas modificaciones.
-Que la ventana pueda estar anclada a la derecha o a la izquierda del programa. Ahora a mi siempre me sale flotante y se me sale de la pantalla. Añadir un scroll si hay mucho elementos para subir o bajar.
-Traducir los texto al ingles que aparecen en castellano valvula, nodo a deposito …
-Cambiar el nombre de la ventana y que sea “Model Tree”.
-Que aparezcan todos los elementos que componen el modelo (tubos, depósitos, turbina, compresor …).
-Que se pueda pinchar con el botón de la derecha sobre cada tipo y que aparezca un menu con:
-Data (para modificar los datos de todos los elementos de este tipo, también se accede con doble click)
-Add (para crear un elemento nuevo de este tipo con exactamente los mismos datos)
-Rename (para que en vez de que ponga type 1 le puedas dar un nombre que te permita identificar los elementos)
-Delete (para borrar todos los elementos de este tipo)MemberHas corregido lo que te comenté de los botones? Además, cuando estás en el estudio paramétrico y cambias el número de casos apretando los botones de subir y bajar el programa se raya. Debe de haber algún problema de índices.
Otra cosa, corrige estos errores pero no cambies la versión, si quieres para diferenciar de una a otra le pones 2.0.2.1, 2.0.2.2 … si no descuadras la versión con el OpenWAM.
MemberYou can modify the engine speed by means of a controller.
MemberIn order to avoid any problem, I recommend using the same value of port diameter, valve diameter and reference diameter. In that case, OpenWAM will use the same discharge coefficients that you write as input data. In other case OpenWAM will recalculate according to the resulting areas.
MemberNo funciona lo de lanzar cálculos desde el WAMer, ya no funcionaba en la versión anterior.
MemberI don’t think so. That function works with matlab 6.5 and with the code compiled with builder 6.0, now we use a newer compiler and current version of matlab is not 6.5. Depending of the version of the both softwares you had to use different libraries but probably it is possible to make run again changing small parts in the code.
MemberThe torque that you obtain at the gear box input is the effective torque.
MemberNet torque is the engine total engine torque produce by the engine combustion, effective torque includes the effect of the mechanical losses. Are you asking this?
MemberConnect the output of a controller (PID, look up table, switch) by dragging and dropping. A red “C” will appear over the valve. Now, if you enter to the information of the valve you will see a new tab called control. There you can decide the parameter that you want to control (lift, valve opening angle and duration)
MemberIn the last versión of OpenWAM
C1=Cw1+Cw2*(Cu(alpha)/Vp)
and
C2=0.001
MemberYou can find a better explanation of the coefficients CW1 and CW2 in SAE Technical Paper 2005-01-0210
MemberHeat transfer fitting of intake coefficient and heat trasnfer fitting of exhaust coefficient are coefficients that multiply heat trasnfer during the intake and the exhaust proceses. By default you can use 1.
Xpe is not used, is an old coefficient, you don’t need to put any specific value.
CW1 and CW2 are coefficients of the Woshni equation. This equation determines the heat transfer cofficient between the gas and the cylinder walls. As default values you can use 1.7 for CW1 and 1 for CW2
MemberThat is a problem of the interface. We will check but if previous version it worked now it should work. Many thanks.
