Dinver - theoretical rayleigh wave ellipticity

Post by lega »

Hi!

How can I show the theoretical rayleigh wave ellipticity curve in dinver as shown in the image ("Sample") below which is taken from an article.

I want to invert ellipticity curve extracted from HVSR using HVTFA. I am using geopsy pack 3.4.2 for HVTFA and the older geopsy pack 2.10.1 for max2curve and dinver.

Thanks for your time!

Hi,

The theoretical ellipticity curve can calculated with gpell if you have a model file (see -h for help and format).

Code: Select all

cat your.model | gpell
If you want to plot it and paste it on top of your experimental curve, you can run

Code: Select all

cat your.model | gpell | figue -c -export toto.layer
Append this .layer file to your experimental plot. If you remove the option -layer, figue will pop up and you can export the layer with the context menu of the plot.

Under Window, you can run these commands inside GeopsyLand provided with geopsy package.

Best regards,

Marc

Hi marc!

Thanks for the response!

I ran the commands in GeopsyLand and got the layer file. However in figue, an error shows as seen in the picture below.

Hi

In general files generated by previous releases can be read in any newer release. The contrary is not true. If you are dealing with several releases at the same time, make sure that the destination application is more recent or at the same version as the source application.

That being said, there might be an error in the generated file (e.g. lack of disk space while generating the file). Can you post your .layer file? Can you also check the versions of the source and destination applications?

Best regards,

Marc

Hi,
Sorry if I enter the discussion.
I wanted to experiment with this approach that I was not familiar with.
I got the layer file using your command line and then I tried to append it on the plot of my experimental curve both with the H / V tool and with figue, but to no avail.
So I added the option -abs to the command for creating the layer file and the problem was solved.

Thanks
Luigi
