Hello All,
 
 I am running the RegCM model, The following are the information that i am using to run the model. 
                            
domain.param

ntypec=   2
iy=         139
jx=         153
ds=        40.00000

clat=      10.00000
clon=      77.50000
iproj=      LAMCON
TRUELATL = 0.5 and TRUELATH = 25
include that valuse and run ( 15 S-35 N and 50 E - 105 E)
 
With above detail ,Model is successfully running.
 
But , I want to run the  model for Map ( 25 S-45 N and 40 E - 115 E) for LAMCON Projection and using same value(.5,25) for truelatL and truelatH. With this value my model is taking too much time or can say model is being hang.
Although i have used different values  for truelatL and truelatH ,but i did not get success to run the model and getting the error exceed the limit.
Please let me know the correct value of trulatL and truelatH for above Map(25 S-45 N and 40 E - 115 E) for LAMCON Projection  and method to calculate the truelatL and truelatH value.
