Thanks! fortran share|improve this forrtl severe (24) question asked Nov 15 '12 at 3:46 amhemad ahmad 2525 add a comment| 1 Answer 1 active oldest votes up vote 2 down vote accepted Two educated guesses The program has tried to read from or write to an array element which doesn't exist, such as the 26th element of a 25-element array. There is a mismatch between the dummy arguments specified for a procedure and the actual arguments in a call to the procedure; for example passing a 4-byte real value when an 8-byte value is expected (or vice-versa) Either of these might lead to an attempt to access a memory location to which the program's process has no rights of access. There are many other possible causes, but in my experience these are the most common errors in Fortran programs which give rise to such error messages. Both of these are easy to spot, you need to (re-)compile your program with compiler options set to check for these conditions share|improve this answer answered Nov 15 '12 at 9:32 High Performance Mark 61.2k462114 add a comment| Your Answer draft saved draft discarded Sign up or log in Sign up using Google Sign up using Facebook Sign up using Email and Password Post as a guest Name Email Post as a guest Name Email discard By posting your answer, you agree to the privacy policy and terms of service.

"forrtl: severe (605): illegal structure for unformatted file". In most cases, the error message will not be helpful to the user since the Fortran messages are intended for the program developer, and a work around may not exist. In some cases though, it may be possible to make an educated guess about why the error occurred based on the error message and the additional insight below. Then by adjusting the input, it may be possible to avoid the error and get results. Tip Some general things to try to bypass these Fortran errors: If the error occurs during the solution of the system of equations, then try a different solver. http://stackoverflow.com/questions/13391267/forrtl-severe-157-program-exception-access-violation (The solver is set somewhere under the "Analysis: Parameters..." dialog.) If the error occurs while reading or writing a file, make sure there is sufficient disk space, that the file size is not above a reasonable limit (such as 2 GB), that the location of the file is accessible (not a read-only media or folder), and so on. Change the element type to something similar. For example, replace a kinematic element with a regular http://download.autodesk.com/us/algor/userguides/mergedProjects/setting_up_the_analysis/Performing_Analysis/General_Fortran_Error_Messages.htm brick element. Replace rigid elements with beam elements. Change the type of load. (Some loads create temporary files, so avoiding the use of a temporary file may avoid the error.) For example, use nodal forces instead of centrifugal loading. If related to a specific file, check that the file exists and at the location specified. For example, if restarting an analysis from another run, make sure the path to the previous run is correct. Whether you are able to bypass the problem or not, an archive of the original model should be created and sent to technical support along with any description that will help to identify the problem. See the page "Getting Started: Starting Autodesk Algor Simulation: How To Get Help" for details. If possible, create the archive with results (so that all files are included). If the archive with results is too large, then send the archive of the model only, but also send the log files. (See the page "Setting Up and Performing the Analysis: File Extensions" for a list of files and their locations.)

Although you didn't say, I'm fairly sure you are using DIGITAL Visual Fortran, since that's an error message we could give. "access violation" means that your program tried to access memory at an forrtl severe (157) invalid or incorrect address. The possible reasons for this are many - almost all of them being coding errors in the application. Some of the possible causes are: 1. Out of bounds array or string references 2. Mismatched argument lists in a call 3. Attempt to store into a constant argument If you are using DVF V6 and run your program under the de{*filter*}, the de{*filter*} will stop at the point of error and this may give you a clue as to what is going wrong. I suggest making sure you have the latest DVF update from our web site (see http://www.*-*-*.com/ ) and if after rebuilding with the latest update the problem is still there, use the de{*filter*} to find out where in your program the error is occurring. If you can't figure it out after that, send a small but complete example attach a copy of BUGREPRT.TXT (from the DF98 folder) completely filled out. -- Fortran Engineering Compaq Computer Corporation, Nashua NH Compaq Fortran web site: http://www.*-*-*.com/ Compaq Fortran Message Board: http://www.*-*-*.com/ :80/mb8
