while running the model, i am getting 2 errors as 1. Error while writing to out of core file, 2. Error while closing the out of core file. could you please tell me what does it mean ? and how to clear this errors?

This could happen if you are running the default solver and there too many meshed elements in your model requiring excessive memory usage. When insufficient memory is available, then hard drive space will be attempted. If the hard drive space is insufficient, then this error will occur.
Could you please attach the model, or maybe an image and a description of what you are modelling with Feko?

I am modeling a field uniformity by the antenna. I placed the antenna, absorbers and near field points in this model to measure the field strength across those points produced by the antenna. please mention if you want to give any suggestions on this model. and please give solution for memory insufficient problem to run this model.

You have 33440 triangles and probably a hundred or so wire segments.
With the default solver you will need roughly 75 GByte of memory. If this is too much for your machine, you can enable the MLFMM solver.

I have run that model for 300MHz by MLFMM solver. It run smoothly. After that i have given 600MHz , error occurs as : " Not enough memory available for dynamic allocation " . Please tell me whats that mean and how to solve that error

You could switch to the SPAI preconditioner.
Some more tips for reducing the computational resources are given in the Appendix of the Altair_Feko_User_Guide.pdf section A-2.10 "How to reduce computational resources"

I tried MLFMM solver and SPAI preconditioner. But I am getting same error as : "Not enough memory available for dynamic allocation" . Please tell me what should i do to clear this problem.

You will either need a machine with more memory, or you will need to coarsen the mesh.
Alternately reduce the model complexity by removing some of the absorber.
