Remote scripting: input values to Linear Elastic soil material

Question

I'm used to model PLAXIS using remote scripting, but has encountered a problem when scripting a linear elastic soil material. I get an error when I input the following, in that order: MaterialName, SoilModel, DrainageType, gammaUnsat, gammaSat, Eref, nu, Gref, Eoed, Vs, Vp, Rinter. The generated soil does not register the stiffnesses. Is there a property too much or a property too less?

Dear Lasse, 
 Even though I was missing a couple of variables (e.g., drainageType) I managed to run the command without an issue. 
 I did notice two things that is incorrect for V22 (which is the version I assumed you work with). 
 
 That is the property "MaterialName". In our latest version that is called "Identification". 
 That is the fact that you want to apply an Rinter but it is a read only. That needs the property "InterfaceStrengthDetermination" to be set to "Manual". 
 
 So, the following worked fine in my case (notice that I replaced the variables with values I thought were right (to run the script): 
 import math

Eref = int(1e6)
nu = 0.3
Eoed = round(((1-nu)*Eref)/((1-2*nu)*(1+nu)))
Gref = round(Eref/(2*(1+nu)))
gamma_sat = 18
gamma_unsat = 20
rho = gamma_unsat/9.8
Vs = math.sqrt(Gref/rho)
Vp = math.sqrt(Eoed/rho)
material = g_i.soilmat()
material.setproperties(
 "Identification", "test",
 # "DefaultValuesAdvanced", True,
 "SoilModel", "Mohr-Coulomb",
 "DrainageType", "Drained",
 "gammaUnsat", gamma_unsat,
 "gammaSat", gamma_sat,
 "Eref", Eref,
 "nu", nu,
 "Gref", Gref,
 "Eoed", Eoed,
 "Vs", Vs,
 "Vp", Vp,
 # "Einc", 0,
 "InterfaceStrengthDetermination", "Manual",
 "Rinter", 0.9)

Hi Again, 
 Thanks a lot for your time. 
 
 I'm sitting with version V21, so the Identification is stil MaterialName, but very good to know once I'm upgrading. :) 
 I tried again using your tips with e.g. "InterfaceStrengthDetermination", "Manual". However, the code did still not run properly. 
 I figured that I could have been something about the number format of the stiffness input, I think there were too many decimals and also some of the input names had a space in them. So when rounding down to 1 decimal and using _ instead of the name, the code started running. 
 
 Luckily this is now resolved, thank you a lot for your attention and your help with the issue.
