  1. Noisy Boundary Condition Signal

    hi there, i think you can do some band pass filtering on the data. Hope the following link may be useful. http://cirpwiki.info/wiki/Utilities But it needs matlab. sorry for that if you dont have one installed on your machine. Karunakar, Scientist, NIOT INDIA
  2. hello every one, i have been doing the following model for some time. the basis of the model is study of impact by artificial reefs on wave induced local currents we have designed a model oriented for peak wave direction We have a model of 5m resolution suggested by the tool box for the wave periods and runup. the wave maker is kept at a depth of 10m. The cell string on sides are purely absorbing and land has a value of 0.1(as suggested in the tutorial). mostly it is in accordance with the bouss2d tutorial. it has given some decent results, till breaking zone, post which does not agree so good with the site data. A model has been constructed with grid size of 1.5m to depict reef width of 3m clearly, with some smoothening in bathymetry. this doesnot show up any result. i've checked the timing of wave maker, model control to we have increased the simulation time upto 3000 steps. but no result has been updated post simulation. what could be the problem Looking for some light. Thanks in advance
  3. sum two time based data sets

    hi there., is it possible to sum two WSE data sets spread in time (between say some time bounds) on a sampled time interval. though resampling option is there is sms, i'm concerned with merging two different data sets. can any one suggest some work out. Thanks in advance, Karunakar kintada
  4. Hi, i'm wondering after seeing the fort 20 file format, whether it can accommodate flux boundaries on two land boundaries?? Can any one put some light on this issue., Thanks in advance Karunakar kintada.
  5. ADCIRC Error

    Sry, writing a query almost after 2 years, i'm an padcirc V47 user. has any one tried tau0=-5 successfully.
  6. Node strings

    thanks todd for the reply., i've even checked the grid file, but there is no information about land boundary. any how, i've remeshed the domain.
  7. Node strings

    hello there, of recent i've encountered a typical problem. i've built a mesh for a domain and done a lot of manual editing on it. unknowingly i've lost the land boundary node string, i've tried changing colors, but of no use. ocean nodestring is visible in blue. so 'm sure land node string is gone. is there any automated way to get it back (please don't suggest i've to manually do it). Thanks in advance, great day. --karunakar kintada Scientist
  8. Compiling PADCIRC on multicore machine

    thanks for the reply., i'm too trying and 'll come back with my successfulness story.
  9. Compiling PADCIRC on multicore machine

    Hi there, Can anyone explain me how to compile padcirc on sgi altix 4700 please.
  10. hi there., 'm sorry, most of my questions seem weird., but i would like to ask., is there any way can compile the padcirc on my computer. i've got good hardware. my WorkStation is 8 intel xeon core based and 'm currently running xp. my colleagues also have the same config - 3 more machines. i've got padcirc code from ftp (one has to place a request for the same). i've read through make complrflags file, but unable to locate windows xp environments. now that i'm interested in compiling the same on this machine and use mpich2 and accelerate the processing. can some one sort out this issue. thanks in advance
  11. Meshing large domains

    Thanks for the suggestion Mr.Zundel., PS: Sorry for the delay., i was offshore for the past few months.
  12. regenerating mesh from previous mesh nodes

    thanks Zundel, the select option was not working earlier and i updated sms to 10.1.11 and found the things back to normal again. for info,i was unable to open the fort.14 file was also(CRC error). with xyz values of the previous mesh, i now got the model back. thank you all.
  13. regenerating mesh from previous mesh nodes

    thanks aquadraht., i dont have the any of the files working because of a problem with my os - encryption. sometime back i've converted the mesh file to scatter point set and saved it as a pts file(saved in my mail). the earlier mesh provided me good validation, so i want to continue with the same. but now i'm stuck up with this problem. is there any way that i can eliminate triangulation in the polygons that were attributed land??
  14. Meshing large domains

    hi rusty., sry for long break. any suggestions??
  15. hi there., i have nodes positional(xyz) data from a previous model(currently project file corrupted)., is there any chance i can regenerate the mesh. the point here is, if i try importing the file as mesh, the triangles are generated even on polygons with land attributes(eg main land and islands). any suggetions please.
