# mia-2dtransformation-to-strain(1)

Green strain tensor.

## NAME

mia-2dtransformation-to-strain - Green strain tensor.

## SYNOPSIS

**mia-2dtransformation-to-strain -i \<in-file\> -o \<out-file\> \[options\]**

## DESCRIPTION

**mia-2dtransformation-to-strain** Evaluate the Green strain tensor corresponding to a given 2D transformation for each grid point.

## OPTIONS

- \-i --in-file=(input, required); io

  input transformation\
    For supported file types see PLUGINS:2dtransform/io

- \-o --out-file=(required, output); string

  output Green's strain tensor

### Help & Info

- \-V --verbose=warning

  verbosity of output, print messages of given level and higher priorities. Supported priorities starting at lowest level are:

  *trace* ‐ Function call trace

  *debug* ‐ Debug output

  *info* ‐ Low level messages

  *message* ‐ Normal messages

  *warning* ‐ Warnings

  *fail* ‐ Report test failures

  *error* ‐ Report errors

  *fatal* ‐ Report only fatal errors
