I am trying to interact with a Simile model from R. I installed the simile package. When I run 
use.simile.at(path.to.installation), I get the following error:

Error in structure(.External(.C_dotTclObjv, objv), class = "tclObj") : 
  [tcl] can't find package Trf.

I am running R version 3.1.1 on a Mac with OSX Yosemite 10.10.2. 

What do I need to do to fix this?

Thanks.

Is Simile 6.2 compatible with Windows XP?

I used to install the Evaluation edition in the computer rooms for my teaching (it worked well with v6.0), but the application quits with a long error message...

Any hint?

Fedora seem to have dropped the Tktable package that is required by Simile.

You have to get it from here (the Enterprise extensions) and install it locally:

http://dl.fedoraproject.org/pub/epel/6/x86_64/tktable-2.9-13.el6.x86_64.rpm

(Replace x86_64 with your architecture if that is different)

Windows users benefit from being able to download a pre-compiled binary distribution of the parameter estimation tool PEST. However, Linux users have to compile it themselves, since the popular Linux distributions do not provide it as a package. Although the instructions for doing this are pretty clear, the procedure fails with many recent Fortran compilers including gfortran, due to new restrictions on program structure.

You will see a series of error messages something like this:

Installing Simile on a Linux box using a package management system is usually pretty straightforward, but there are a couple of issues that cause problems if you are using this popular release of Ubuntu. Oddly they are unique to 12.04 LTS (Precise) -- they do not occur on earlier or later Ubuntu versions.

Hi,

I am having problems understanding how to use the 3D viewer helper. I created a 2 x 2 grid, each cell representing the amount of biomass produced on a model run with different initial values. I intend to use the third dimension to better observe differences in biomass among cells.

I am trying to use the "table function" instead of the "graph function" because to me it seems more reasonable to have a set of data points lying on a defined function instead of using optical fitting in a graph. Though, I could not find any option that allows for interpolation between two points in the "table function" while this option is provided in the "graph function". Is there really no option for interpolation between the data points provided using the "table function"?

Thanks, Georg

After encountering an unexpected error when running an old model built with Simile 5.3, I discovered that the element function did not work anymore with such a complex syntax (as examplified in the documentation of the function for advanced users!):

element([[5,7],[1,4],[8,5]], [3,3,2,2])

Only an equation such as element([[5,7],[1,4],[8,5]], 1) is now accepted in Simile 5.8 and the last 5.8p4!

Could you please tell me how to solve this problem?...

Thanks,

François

I tried to test some part of SUCROS  model.

When I got the rate of development stage, the results were different by changing time step from 1 to 0.1.

I also made simple models to know the reason.

But I can't understand well.

I attached simple models.

I have some Fortran code I'd like to implement in Simile, but I am a bit stuck on how to handle a Do ... Until loop. What I'm actually doing is sorting out an allocation across array elements, so it all has to happen within a single timestep. I'm sure Robert sent me an example a few years ago using a conditional instance submodel, but I can't access my old email archive at the mo. Ideas welcome. Thanks, Ed.
