I will introduce the MSC.Marc/Mentat finite element solver, which is installed on the virtual machine presented below. Please check that you are able to boot up the virtual machine, and that the present website is reachable from within the virtual machine itself (i.e. that the v.m. is online).

===== Virtual machine for the lab sessions =====

A newer virtual machine, which also contains the MSC.Adams 2017.2 software employed in dedicated Vehicle Dynamics seminars, is available {{https://cdm.ing.unimo.it/dokuwiki/restricted/vbox2020|here}}.

<hidden Click here for the former virtual machine instructions.>download Oracle virtualbox [[https://www.virtualbox.org/|link]]

download the virtual machine image from [[restricted:debvboxdownload|>>> here <<<]]

[[https://cdm.ing.unimo.it/user-ldap-change-pwd/indexChangeLdapPassword.php|Register]] your user for the license server network port forwarding (aka poor man's VPN).




Enable the [[https://en.wikipedia.org/wiki/X86_virtualization|hardware support to virtualization]] your cpu is featured with from the BIOS/UEFI menu, otherwise the following error will be raised

{{:wikifemfuchde2019:virtualbox_vt-x_amd-v_error-01_dialog-100612958-large.idge.png|}}

In the case you are unable to make the virtual machine run, a //rather experimental// terminal server based on x2go is available. 

A few video instructions:

===== Lecture notes =====
Lecture notes contain parts that were not discussed in the recorded lessons; __those parts will not be asked during the exam__. Also, lecture notes will be subjected to improvement where appropriate.
  * {{ :wikipaom2020:lecturenotes_2020-06-05a.pdf |}}, first attempt for a final version;


===== Exam =====
Notes for the exam.

The exam will consist of an interview of approximate 30-40 minutes in which you will be asked to
  * comment, modify or complete finite element models in the MSC.Marc / Mentat environment, chosen - with possible variations - among those carried out in class or proposed as [[wikifemfuchde2020:examExercises|wikifemfuchde2020:examExercises]].
  * comment, modify or complete maxima spreadsheets chosen - with possible variations - among those carried out in class or proposed as [[wikifemfuchde2020:examExercises|wikifemfuchde2020:examExercises]].
  * answer a couple of theoretical questions, according to the final detailed program (which will be uploaded as soon as the lessons are completed). An authorized cheatsheet will be provided for use during the test, reporting the most relevant formulas from the PDF handouts, but no comments.

Technical details will be provided for sharing a graphical terminal on which you may operate jointly with the teacher, together with the links for accessing the exam sessions.

The student is also asked to prepare paper and stationery in order illustrate the answers with drawings and graphics; these sketches will then be shown at the webcam, or sent via instant messaging (google hangout with unimore account login is ok) from a mobile phone.

According to the current organization, exam sessions have been opened on every Friday in June / July, with a further turn on the subsequent Monday, if needed.

To guarantee each student the access to at least one exam session in June and one exam session in July (see teaching regulations), students are asked to ** refrain from enrolling ** to more than one exam session in two weeks (for example, if a student signs up for the June 26 session, he will refrain from signing up for the subsequent July 3 session), and more than three sessions in two months.
