Hello,
I am a new guy to CAESAR II. Currently I am doing the seismic analysis of a class 3 piping system using CAESAR II 5.0. It's a pain for me to prepare a self-defined Response spectra in CAESAR II. Is there any detailed manual that I can follow to prepare this dynamic analysis. I read the user's guide and other guides, it seems the describtions are not clear.
Thank you.

The example job NUREG9 shows how to setup the input for both an "envelope" approach and an ISM approach. The spectrum data is simply two columns of numbers, and this should be provided to you.

Alternatively you could always let CAESAR II generate an ASCE spectra.

What is your difficulty?

Thank you, Richard.

I have a specified spectra for my system, I input this spectra in the Spectrum definitions. I read the data from a file as follows:
0.1 5.94
0.22 29.67
0.5 59.42
1.0 124.62
6.57 463.00
21.37 463.00
25 118.84
33 17.83
100 17.83

When I check the input, it come out the folloing messages:
33 , 17.83
100 , 17.83
*** ERROR *** Spectrum/Time History case 1 is empty.
*** NOTE *** Input check terminated due to fatal errors

Everytime I start a new spectrum, it automaticaly starts from Case 2 rather than Case 1. I don't know if that is the reason.

Thanks,
Bing

My first suggestion is to put a "decimal point" in the values 25, 33, and 100. If that doesn't resolve the issue, send you job files to "techsupport@coade.com" so we can take a look.

Also, please advise in the e-mail exactly what Version and Build of CAESAR II you are using.

It does not work, aonther errors come out.

I even try to input the data one by one manually. It still have error message said "*****ERROR*****Invalid Entry Line #2"...and so on. Sometime it comes out with the error of "The values in the left column must be in ascending order", but it does be ascending ordered.

The version is CAESAR II 5.00.4

Thanks

Send us your ".CAESAR II" file.

I have sent the model to you yesterday. Did you get a chance to look at it? I really appreciate your time and effort.
The problem I met, hopefully, is not caused by the bug.

I'm having a similar problem when attempting to run a "Relief Valve Spectrum". In summary, when wanting to perform a "relief spectrum", one would tab through the various menus and respond to the prompts but upon reviewing the inputs and back tabbing through the same menus, the inputs are completely "scrambled" and don't even closely resemble the original inputs when first tabbing through. I have sent my ".CAESAR II" file to techsupport and am anxiously waiting for a reply.

Ok, the problem seems to be predicated by trying to delete all of the text from the dialogs. DON'T DO THIS!!!!

I'll try to get a build out next week or the week after, once we finish testing.

If you corrupt your dynamic input, there is no recovery. You'll have to delete the _7 file, then reenter the dynamic input.

My problem has been solved now. However I got two other issues coming out, I have sent a seperate email to you.
Thank you.

Hello to Everyone
I am also a new user and i experience the same issue when trying to perform a seismic analysis(i deleted the predefined input), Is there any news to when the build is to be published?
Also is the _7 file u specifie a CAESAR II producted file-an extension, or a user-created file for that specific job? cause i dont seem to be able to locate it and delete it so to re enter the dynamic input and continue my work.

Thanks in advance

The build is in testing and we hope to release it on the 5th (of October). The _7 is a CAESAR II extension.

With Version 5.00, all of the CAESAR II files are zipped into the ".CAESAR II" archive, so there is only one file to deal with (as far as saving or e-mailing). To manipulate the actual component files, you need to enter on of the CAESAR II modules - for instance Piping Input. Enter the input, then using Windows Explorer, you should be able to see all the component files - because the archive has been exploded. Now you should be able to delete the _7 file.

If you don't want the examples and default data, turn it off in the Configuration. Go to the Miscellaneous Tab and change the setting for the Dynamic Example Input Text directive.

Richard,

I met the same problem again even my current version is CAESAR II 5.005, (Build 061005).

The error message is as follows when I prepared the response septrum by reading in the data from a text file.

*** ERROR *** Spectrum/Time History case 1 is empty.

Please give advice. Thank you.

Send in the "CAESAR II" file and we'll take a look. Did you create the dynamic input before or after applying the 061005 build?
